+Subject: afs: afs_write_end() should change i_size under the right lock
+
+From: David Howells <dhowells@redhat.com>
+
+[ Upstream commit 1f32ef79897052ef7d3d154610d8d6af95abde83 ]
+
+Fix afs_write_end() to change i_size under vnode->cb_lock rather than
+->wb_lock so that it doesn't race with afs_vnode_commit_status() and
+afs_getattr().
+
+The ->wb_lock is only meant to guard access to ->wb_keys which isn't
+accessed by that piece of code.

+Subject: afs: Always include dir in bulk status fetch from afs_do_lookup()
+
+From: David Howells <dhowells@redhat.com>
+
+[ Upstream commit 13fcc6356a94558a0a4857dc00cd26b3834a1b3e ]
+
+When a lookup is done in an AFS directory, the filesystem will speculate
+and fetch up to 49 other statuses for files in the same directory and fetch
+those as well, turning them into inodes or updating inodes that already
+exist.
+
+However, occasionally, a callback break might go missing due to NAT timing
+out, but the afs filesystem doesn't then realise that the directory is not
+up to date.
+
+Alleviate this by using one of the status slots to check the directory in
+which the lookup is being done.

+Subject: afs: Fix EOF corruption
+
+From: David Howells <dhowells@redhat.com>
+
+[ Upstream commit 3f4aa981816368fe6b1d13c2bfbe76df9687e787 ]
+
+When doing a partial writeback, afs_write_back_from_locked_page() may
+generate an FS.StoreData RPC request that writes out part of a file when a
+file has been constructed from pieces by doing seek, write, seek, write,
+... as is done by ld.
+
+The FS.StoreData RPC is given the current i_size as the file length, but
+the server basically ignores it unless the data length is 0 (in which case
+it's just a truncate operation). The revised file length returned in the
+result of the RPC may then not reflect what we suggested - and this leads
+to i_size getting moved backwards - which causes issues later.
+
+Fix the client to take account of this by ignoring the returned file size
+unless the data version number jumped unexpectedly - in which case we're
+going to have to clear the pagecache and reload anyway.
+
+This can be observed when doing a kernel build on an AFS mount. The
+following pair of commands produce the issue:
+
+ ld -m elf_x86_64 -z max-page-size=0x200000 --emit-relocs \
+ -T arch/x86/realmode/rm/realmode.lds \
+ arch/x86/realmode/rm/header.o \
+ arch/x86/realmode/rm/trampoline_64.o \
+ arch/x86/realmode/rm/stack.o \
+ arch/x86/realmode/rm/reboot.o \
+ -o arch/x86/realmode/rm/realmode.elf
+ arch/x86/tools/relocs --realmode \
+ arch/x86/realmode/rm/realmode.elf \
+ >arch/x86/realmode/rm/realmode.relocs
+
+This results in the latter giving:
+
+ Cannot read ELF section headers 0/18: Success
+
+as the realmode.elf file got corrupted.
+
+The sequence of events can also be driven with:
+
+ xfs_io -t -f \
+ -c "pwrite -S 0x58 0 0x58" \
+ -c "pwrite -S 0x59 10000 1000" \
+ -c "close" \

+
+From: Takashi Sakamoto <o-takashi@sakamocchi.jp>
+
+[ Upstream commit 8304cf77c92038cd1c50c27b69d30be695cc8003 ]
+
+Although the value of FDF is used just for outgoing stream, the assignment
+to union member is done for both directions of stream. At present this
+causes no issue because the value of same position is reassigned later for
+opposite stream. However, it's better to add if statement.

+Subject: ALSA: usb-audio: Add duplex sound support for USB devices using
+ implicit feedback
+
+From: Erwin Burema <e.burema@gmail.com>
+
+[ Upstream commit 10ce77e4817fef99e1166be7e6685a80c63bf77f ]
+
+For USB sound devices using implicit feedback the endpoint used for
+this feedback should be able to be opened twice, once for required
+feedback and second time for audio data. This way these devices can be
+put in duplex audio mode. Since this only works if the settings of the
+endpoint don't change a check is included for this.
+
+This fixes bug 207023 ("MOTU M2 regression on duplex audio") and
+should also fix bug 103751 ("M-Audio Fast Track Ultra usb audio device
+will not operate full-duplex")

+Subject: ALSA: usb-audio: Improve frames size computation
+
+From: Alexander Tsoy <alexander@tsoy.me>
+
+[ Upstream commit f0bd62b64016508938df9babe47f65c2c727d25c ]
+
+For computation of the the next frame size current value of fs/fps and
+accumulated fractional parts of fs/fps are used, where values are stored
+in Q16.16 format. This is quite natural for computing frame size for
+asynchronous endpoints driven by explicit feedback, since in this case
+fs/fps is a value provided by the feedback endpoint and it's already in
+the Q format. If an error is accumulated over time, the device can
+adjust fs/fps value to prevent buffer overruns/underruns.
+
+But for synchronous endpoints the accuracy provided by these computations
+is not enough. Due to accumulated error the driver periodically produces
+frames with incorrect size (+/- 1 audio sample).
+
+This patch fixes this issue by implementing a different algorithm for
+frame size computation. It is based on accumulating of the remainders
+from division fs/fps and it doesn't accumulate errors over time. This
+new method is enabled for synchronous and adaptive playback endpoints.

+Subject: apparmor: check/put label on apparmor_sk_clone_security()
+
+From: Mauricio Faria de Oliveira <mfo@canonical.com>
+
+[ Upstream commit 3b646abc5bc6c0df649daea4c2c976bd4d47e4c8 ]
+
+Currently apparmor_sk_clone_security() does not check for existing
+label/peer in the 'new' struct sock; it just overwrites it, if any
+(with another reference to the label of the source sock.)
+
+ static void apparmor_sk_clone_security(const struct sock *sk,
+ struct sock *newsk)
+ {
+ struct aa_sk_ctx *ctx = SK_CTX(sk);
+ struct aa_sk_ctx *new = SK_CTX(newsk);
+
+ new->label = aa_get_label(ctx->label);
+ new->peer = aa_get_label(ctx->peer);
+ }
+
+This might leak label references, which might overflow under load.
+Thus, check for and put labels, to prevent such errors.
+
+Note this is similarly done on:
+
+ static int apparmor_socket_post_create(struct socket *sock, ...)
+ ...
+ if (sock->sk) {
+ struct aa_sk_ctx *ctx = SK_CTX(sock->sk);
+
+ aa_put_label(ctx->label);
+ ctx->label = aa_get_label(label);
+ }
+ ...
+
+Context:
+-------
+
+The label reference count leak is observed if apparmor_sock_graft()
+is called previously: this sets the 'ctx->label' field by getting
+a reference to the current label (later overwritten, without put.)
+
+ static void apparmor_sock_graft(struct sock *sk, ...)
+ {
+ struct aa_sk_ctx *ctx = SK_CTX(sk);
+
+ if (!ctx->label)
+ ctx->label = aa_get_current_label();
+ }
+
+And that is the case on crypto/af_alg.c:af_alg_accept():
+
+ int af_alg_accept(struct sock *sk, struct socket *newsock, ...)
+ ...
+ struct sock *sk2;
+ ...
+ sk2 = sk_alloc(...);
+ ...
+ security_sock_graft(sk2, newsock);
+ security_sk_clone(sk, sk2);
+ ...
+
+Apparently both calls are done on their own right, especially for
+other LSMs, being introduced in 2010/2014, before apparmor socket
+mediation in 2017 (see commits [1,2,3,4]).
+
+So, it looks OK there! Let's fix the reference leak in apparmor.

+Subject: apparmor: fix introspection of of task mode for unconfined tasks
+
+From: John Johansen <john.johansen@canonical.com>
+
+[ Upstream commit dd2569fbb053719f7df7ef8fdbb45cf47156a701 ]
+
+Fix two issues with introspecting the task mode.
+
+1. If a task is attached to a unconfined profile that is not the
+ ns->unconfined profile then. Mode the mode is always reported
+ as -
+
+ $ ps -Z
+ LABEL PID TTY TIME CMD
+ unconfined 1287 pts/0 00:00:01 bash
+ test (-) 1892 pts/0 00:00:00 ps
+
+ instead of the correct value of (unconfined) as shown below
+
+ $ ps -Z
+ LABEL PID TTY TIME CMD
+ unconfined 2483 pts/0 00:00:01 bash
+ test (unconfined) 3591 pts/0 00:00:00 ps
+
+2. if a task is confined by a stack of profiles that are unconfined
+ the output of label mode is again the incorrect value of (-) like
+ above, instead of (unconfined). This is because the visibile
+ profile count increment is skipped by the special casing of
+ unconfined.

+Subject: ARM: dts: meson: Switch existing boards with RGMII PHY to "rgmii-id"
+
+From: Martin Blumenstingl <martin.blumenstingl@googlemail.com>
+
+[ Upstream commit 005231128e9e97461e81fa32421957a7664317ca ]
+
+Let the PHY generate the RX and TX delay on the Odroid-C1 and MXIII
+Plus.
+
+Previously we did not know that these boards used an RX delay. We
+assumed that setting the TX delay on the MAC side It turns out that
+these boards also require an RX delay of 2ns (verified on Odroid-C1,
+but the u-boot code uses the same setup on both boards). Ethernet only
+worked because u-boot added this RX delay on the MAC side.
+
+The 4ns TX delay was also wrong and the result of using an unsupported
+RGMII TX clock divider setting. This has been fixed in the driver with
+commit bd6f48546b9cb7 ("net: stmmac: dwmac-meson8b: Fix the RGMII TX
+delay on Meson8b/8m2 SoCs").
+
+Switch to phy-mode "rgmii-id" to let the PHY side handle all the delays,
+(as recommended by the Ethernet maintainers anyways) to correctly
+describe the need for a 2ns RX as well as 2ns TX delay on these boards.
+This fixes the Ethernet performance on Odroid-C1 where there was a huge
+amount of packet loss when transmitting data due to the incorrect TX
+delay.

+Subject: ARM: integrator: Add some Kconfig selections
+
+From: Linus Walleij <linus.walleij@linaro.org>
+
+[ Upstream commit d2854bbe5f5c4b4bec8061caf4f2e603d8819446 ]
+
+The CMA and DMA_CMA Kconfig options need to be selected
+by the Integrator in order to produce boot console on some
+Integrator systems.
+
+The REGULATOR and REGULATOR_FIXED_VOLTAGE need to be
+selected in order to boot the system from an external
+MMC card when using MMCI/PL181 from the device tree
+probe path.
+
+Select these things directly from the Kconfig so we are
+sure to be able to bring the systems up with console
+from any device tree.

+
+Use sdhci-caps-mask to forbid SDR104 mode on the SDIO capable SDHCI
+controller. Without this the device cannot pass electromagnetic

+Subject: arm64: dts: fvp: Fix GIC child nodes
+
+From: Andre Przywara <andre.przywara@arm.com>
+
+[ Upstream commit 78631aecc52c4b2adcf611769df2ff9c67ac16d0 ]
+
+The GIC DT nodes for the fastmodels were not fully compliant with the
+DT binding, which has certain expectations about child nodes and their
+size and address cells values.
+
+Use smaller #address-cells and #size-cells values, as the binding
+requests, and adjust the reg properties accordingly.
+This requires adjusting the interrupt nexus nodes as well, as one
+field of the interrupt-map property depends on the GIC's address-size.
+
+Since the .dts files share interrupt nexus nodes across different
+interrupt controllers (GICv2 vs. GICv3), we need to use the only
+commonly allowed #address-size value of <1> for both.

+
+[ Upstream commit bb5cce12ac717c7462217cd493ed701d12d6dbce ]
+
+The Arm Ltd. boards were using an outdated address convention in the DT
+node names, by separating the high from the low 32-bits of an address by
+a comma.
+
+Remove the comma from the node name suffix to be DT spec compliant.

+
+[ Upstream commit a78aee9e434932a500db36cc6d88daeff3745e9f ]
+
+The GIC DT nodes for the Juno boards were not fully compliant with
+the DT binding, which has certain expectations about child nodes and
+their size and address cells values.
+
+Use smaller #address-cells and #size-cells values, as the binding
+requests, and adjust the reg properties accordingly.
+This requires adjusting the interrupt nexus nodes as well, as one
+field of the interrupt-map property depends on the GIC's address-size.

+Subject: arm64: dts: meson: fixup SCP sram nodes
+
+From: Neil Armstrong <narmstrong@baylibre.com>
+
+[ Upstream commit 9ecded10b4b6af238da0c86197b0418912e7513e ]
+
+The GX and AXG SCP sram nodes were using invalid compatible and
+node names for the sram entries.
+
+Fixup the sram entries node names, and use proper compatible for them.
+
+It notably fixes:
+sram@c8000000: 'scp-shmem@0', 'scp-shmem@200' do not match any of the regexes: '^([a-z]*-)?sram(-section)?@[a-f0-9]+$', 'pinctrl-[0-9]+'

+Subject: arm64: dts: qcom: fix pm8150 gpio interrupts
+
+From: Jonathan Marek <jonathan@marek.ca>
+
+[ Upstream commit 61d2ca503d0b55d2849fd656ce51d8e1e9ba0b6c ]
+
+This was mistakenly copied from the downstream dts, however the upstream
+driver works differently.
+
+I only tested this with the pm8150_gpios node (used with volume button),
+but the 2 others should be the same.
+
+Fixes: e92b61c8e775 ("arm64: dts: qcom: pm8150l: Add base dts file")

+Subject: arm64: hw_breakpoint: Don't invoke overflow handler on uaccess
+ watchpoints
+
+From: Will Deacon <will@kernel.org>
+
+[ Upstream commit 24ebec25fb270100e252b19c288e21bd7d8cc7f7 ]
+
+Unprivileged memory accesses generated by the so-called "translated"
+instructions (e.g. STTR) at EL1 can cause EL0 watchpoints to fire
+unexpectedly if kernel debugging is enabled. In such cases, the
+hw_breakpoint logic will invoke the user overflow handler which will
+typically raise a SIGTRAP back to the current task. This is futile when
+returning back to the kernel because (a) the signal won't have been
+delivered and (b) userspace can't handle the thing anyway.
+
+Avoid invoking the user overflow handler for watchpoints triggered by
+kernel uaccess routines, and instead single-step over the faulting
+instruction as we would if no overflow handler had been installed.
+
+(Fixes tag identifies the introduction of unprivileged memory accesses,
+ which exposed this latent bug in the hw_breakpoint code)

+Subject: arm64: tegra: Fix ethernet phy-mode for Jetson Xavier
+
+From: Jon Hunter <jonathanh@nvidia.com>
+
+[ Upstream commit bba25915b172c72f6fa635f091624d799e3c9cae ]
+
+The 'phy-mode' property is currently defined as 'rgmii' for Jetson
+Xavier. This indicates that the RGMII RX and TX delays are set by the
+MAC and the internal delays set by the PHY are not used.
+
+If the Marvell PHY driver is enabled, such that it is used and not the
+generic PHY, ethernet failures are seen (DHCP is failing to obtain an
+IP address) and this is caused because the Marvell PHY driver is
+disabling the internal RX and TX delays. For Jetson Xavier the internal
+PHY RX and TX delay should be used and so fix this by setting the
+'phy-mode' to 'rgmii-id' and not 'rgmii'.

+Subject: ASoC: core: only convert non DPCM link to DPCM link
+
+From: Bard Liao <yung-chuan.liao@linux.intel.com>
+
+[ Upstream commit 607fa205a7e4dfad28b8a67ab1c985756ddbccb0 ]
+
+Additional checks for valid DAIs expose a corner case, where existing
+BE dailinks get modified, e.g. HDMI links are tagged with
+dpcm_capture=1 even if the DAIs are for playback.
+
+This patch makes those changes conditional and flags configuration
+issues when a BE dailink is has no_pcm=0 but dpcm_playback or
+dpcm_capture=1 (which makes no sense).
+
+As discussed on the alsa-devel mailing list, there are redundant flags
+for dpcm_playback, dpcm_capture, playback_only, capture_only. This
+will have to be cleaned-up in a future update. For now only correct
+and flag problematic configurations.

+Subject: ASoC: davinci-mcasp: Fix dma_chan refcnt leak when getting dma type
+
+From: Xiyu Yang <xiyuyang19@fudan.edu.cn>
+
+[ Upstream commit a697ae6ea56e23397341b027098c1b11d9ab13da ]
+
+davinci_mcasp_get_dma_type() invokes dma_request_chan(), which returns a
+reference of the specified dma_chan object to "chan" with increased
+refcnt.
+
+When davinci_mcasp_get_dma_type() returns, local variable "chan" becomes
+invalid, so the refcount should be decreased to keep refcount balanced.
+
+The reference counting issue happens in one exception handling path of
+davinci_mcasp_get_dma_type(). When chan device is NULL, the function
+forgets to decrease the refcnt increased by dma_request_chan(), causing
+a refcnt leak.
+
+Fix this issue by calling dma_release_channel() when chan device is
+NULL.

+
+From: Hans de Goede <hdegoede@redhat.com>
+
+[ Upstream commit 79d4f823a06796656289f97b922493da5690e46c ]
+
+The Asus T101HA uses the default jack-detect mode 3, but instead of
+using an analog microphone it is using a DMIC on dmic-data-pin 1,
+like the Asus T100HA. Note unlike the T100HA its jack-detect is not
+inverted.
+
+Add a DMI quirk with the correct settings for this model.

+
+[ Upstream commit 03990fd58d2b7c8f7d53e514ba9b8749fac260f9 ]
+
+If an error occurs after the call to 'omap_mcbsp_init()', the reference to
+'mcbsp->fclk' must be decremented, as already done in the remove function.
+
+This can be achieved easily by using the devm_ variant of 'clk_get()'
+when the reference is taken in 'omap_mcbsp_init()'
+
+This fixes the leak in the probe and has the side effect to simplify both
+the error handling path of 'omap_mcbsp_init()' and the remove function.

+
+From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
+
+[ Upstream commit 4e8748fcaeec073e3ba794871ce86c545e4f961f ]
+
+There are 2 issues here:
+ - if one of the 'of_parse_phandle' fails, calling 'mop500_of_node_put()'
+ is a no-op because the 'mop500_dai_links' structure has not been
+ initialized yet, so the referenced are not decremented
+ - The reference stored in 'mop500_dai_links[i].codecs' is refcounted
+ only once in the probe and must be decremented only once.

+Subject: bcache: fix potential deadlock problem in btree_gc_coalesce
+
+From: Zhiqiang Liu <liuzhiqiang26@huawei.com>
+
+[ Upstream commit be23e837333a914df3f24bf0b32e87b0331ab8d1 ]
+
+coccicheck reports:
+ drivers/md//bcache/btree.c:1538:1-7: preceding lock on line 1417
+
+In btree_gc_coalesce func, if the coalescing process fails, we will goto
+to out_nocoalesce tag directly without releasing new_nodes[i]->write_lock.
+Then, it will cause a deadlock when trying to acquire new_nodes[i]->
+write_lock for freeing new_nodes[i] before return.
+
+btree_gc_coalesce func details as follows:
+ if alloc new_nodes[i] fails:
+ goto out_nocoalesce;
+ // obtain new_nodes[i]->write_lock
+ mutex_lock(&new_nodes[i]->write_lock)
+ // main coalescing process
+ for (i = nodes - 1; i > 0; --i)
+ [snipped]
+ if coalescing process fails:
+ // Here, directly goto out_nocoalesce
+ // tag will cause a deadlock
+ goto out_nocoalesce;
+ [snipped]
+ // release new_nodes[i]->write_lock
+ mutex_unlock(&new_nodes[i]->write_lock)
+ // coalesing succ, return
+ return;
+out_nocoalesce:
+ btree_node_free(new_nodes[i]) // free new_nodes[i]
+ // obtain new_nodes[i]->write_lock
+ mutex_lock(&new_nodes[i]->write_lock);
+ // set flag for reuse
+ clear_bit(BTREE_NODE_dirty, &ew_nodes[i]->flags);
+ // release new_nodes[i]->write_lock
+ mutex_unlock(&new_nodes[i]->write_lock);
+
+To fix the problem, we add a new tag 'out_unlock_nocoalesce' for
+releasing new_nodes[i]->write_lock before out_nocoalesce tag. If
+coalescing process fails, we will go to out_unlock_nocoalesce tag
+for releasing new_nodes[i]->write_lock before free new_nodes[i] in
+out_nocoalesce tag.

+Subject: block: Fix use-after-free in blkdev_get()
+
+From: Jason Yan <yanaijie@huawei.com>
+
+[ Upstream commit 2d3a8e2deddea6c89961c422ec0c5b851e648c14 ]
+
+In blkdev_get() we call __blkdev_get() to do some internal jobs and if
+there is some errors in __blkdev_get(), the bdput() is called which
+means we have released the refcount of the bdev (actually the refcount of
+the bdev inode). This means we cannot access bdev after that point. But
+acctually bdev is still accessed in blkdev_get() after calling
+__blkdev_get(). This results in use-after-free if the refcount is the
+last one we released in __blkdev_get(). Let's take a look at the
+following scenerio:
+
+ CPU0 CPU1 CPU2
+blkdev_open blkdev_open Remove disk
+ bd_acquire
+ blkdev_get
+ __blkdev_get del_gendisk
+ bdev_unhash_inode
+ bd_acquire bdev_get_gendisk
+ bd_forget failed because of unhashed
+ bdput

+

+
+[ Upstream commit 33a7c831565c43a7ee2f38c7df4c4a40e1dfdfed ]
+
+When sockhash gets destroyed while sockets are still linked to it, we will
+walk the bucket lists and delete the links. However, we are not freeing the
+list elements after processing them, leaking the memory.
+
+The leak can be triggered by close()'ing a sockhash map when it still
+contains sockets, and observed with kmemleak:

+
+From: Jakub Sitnicki <jakub@cloudflare.com>
+
+[ Upstream commit 75e68e5bf2c7fa9d3e874099139df03d5952a3e1 ]
+
+We can end up modifying the sockhash bucket list from two CPUs when a
+sockhash is being destroyed (sock_hash_free) on one CPU, while a socket
+that is in the sockhash is unlinking itself from it on another CPU
+it (sock_hash_delete_from_link).
+
+This results in accessing a list element that is in an undefined state as
+reported by KASAN:

+
+Fix it by reintroducing spin-lock protected critical section around the
+code that removes the elements from the bucket on sockhash free.
+
+To do that we also need to defer processing of removed elements, until out
+of atomic context so that we can unlink the socket from the map when

+Subject: bpf/sockmap: Fix kernel panic at __tcp_bpf_recvmsg
+
+From: dihu <anny.hu@linux.alibaba.com>
+
+[ Upstream commit 487082fb7bd2a32b66927d2b22e3a81b072b44f0 ]
+
+When user application calls read() with MSG_PEEK flag to read data
+of bpf sockmap socket, kernel panic happens at
+__tcp_bpf_recvmsg+0x12c/0x350. sk_msg is not removed from ingress_msg
+queue after read out under MSG_PEEK flag is set. Because it's not
+judged whether sk_msg is the last msg of ingress_msg queue, the next
+sk_msg may be the head of ingress_msg queue, whose memory address of
+sg page is invalid. So it's necessary to add check codes to prevent
+this problem.

+Subject: ceph: don't return -ESTALE if there's still an open file
+
+From: Luis Henriques <lhenriques@suse.com>
+
+[ Upstream commit 878dabb64117406abd40977b87544d05bb3031fc ]
+
+Similarly to commit 03f219041fdb ("ceph: check i_nlink while converting
+a file handle to dentry"), this fixes another corner case with
+name_to_handle_at/open_by_handle_at. The issue has been detected by
+xfstest generic/467, when doing:
+
+ - name_to_handle_at("/cephfs/myfile")
+ - open("/cephfs/myfile")
+ - unlink("/cephfs/myfile")
+ - sync; sync;
+ - drop caches
+ - open_by_handle_at()
+
+The call to open_by_handle_at should not fail because the file hasn't been
+deleted yet (only unlinked) and we do have a valid handle to it. -ESTALE
+shall be returned only if i_nlink is 0 *and* i_count is 1.
+
+This patch also makes sure we have LINK caps before checking i_nlink.

+Subject: cifs: set up next DFS target before generic_ip_connect()
+
+From: Paulo Alcantara <pc@cjr.nz>
+
+[ Upstream commit aaa3aef34d3ab9499a5c7633823429f7a24e6dff ]
+
+If we mount a very specific DFS link
+
+ \\FS0.FOO.COM\dfs\link -> \FS0\share1, \FS1\share2
+
+where its target list contains NB names ("FS0" & "FS1") rather than
+FQDN ones ("FS0.FOO.COM" & "FS1.FOO.COM"), we end up connecting to
+\FOO\share1 but server->hostname will have "FOO.COM". The reason is
+because both "FS0" and "FS0.FOO.COM" resolve to same IP address and
+they share same TCP server connection, but "FS0.FOO.COM" was the first
+hostname set -- which is OK.
+
+However, if the echo thread timeouts and we still have a good
+connection to "FS0", in cifs_reconnect()
+
+ rc = generic_ip_connect(server) -> success
+ if (rc) {
+ ...
+ reconn_inval_dfs_target(server, cifs_sb, &tgt_list,
+ &tgt_it);
+ ...
+ }
+ ...
+
+it successfully reconnects to "FS0" server but does not set up next
+DFS target - which should be the same target server "\FS0\share1" -
+and server->hostname remains set to "FS0.FOO.COM" rather than "FS0",
+as reconn_inval_dfs_target() would have it set to "FS0" if called
+earlier.
+
+Finally, in __smb2_reconnect(), the reconnect of tcons would fail
+because tcon->ses->server->hostname (FS0.FOO.COM) does not match DFS
+target's hostname (FS0).
+
+Fix that by calling reconn_inval_dfs_target() before
+generic_ip_connect() so server->hostname will get updated correctly
+prior to reconnecting its tcons in __smb2_reconnect().
+
+With "cifs: handle hostnames that resolve to same ip in failover"
+patch
+
+ - The above problem would not occur.
+ - We could save an DNS query to find out that they both resolve to
+ the same ip address.

+Subject: clk: bcm2835: Fix return type of bcm2835_register_gate
+
+From: Nathan Chancellor <natechancellor@gmail.com>
+
+[ Upstream commit f376c43bec4f8ee8d1ba5c5c4cfbd6e84fb279cb ]
+
+bcm2835_register_gate is used as a callback for the clk_register member
+of bcm2835_clk_desc, which expects a struct clk_hw * return type but
+bcm2835_register_gate returns a struct clk *.
+
+This discrepancy is hidden by the fact that bcm2835_register_gate is
+cast to the typedef bcm2835_clk_register by the _REGISTER macro. This
+turns out to be a control flow integrity violation, which is how this
+was noticed.
+
+Change the return type of bcm2835_register_gate to be struct clk_hw *
+and use clk_hw_register_gate to do so. This should be a non-functional
+change as clk_register_gate calls clk_hw_register_gate anyways but this
+is needed to avoid issues with further changes.

+Subject: clk: meson: meson8b: Fix the first parent of vid_pll_in_sel
+
+From: Martin Blumenstingl <martin.blumenstingl@googlemail.com>
+
+[ Upstream commit da1978ac3d6cf278dedf5edbf350445a0fff2f08 ]
+
+Use hdmi_pll_lvds_out as parent of the vid_pll_in_sel clock. It's not
+easy to see that the vendor kernel does the same, but it actually does.
+meson_clk_pll_ops in mainline still cannot fully recalculate all rates
+from the HDMI PLL registers because some register bits (at the time of
+writing it's unknown which bits are used for this) double the HDMI PLL
+output rate (compared to simply considering M, N and FRAC) for some (but
+not all) PLL settings.
+
+Update the vid_pll_in_sel parent so our clock calculation works for
+simple clock settings like the CVBS output (where no rate doubling is
+going on). The PLL ops need to be fixed later on for more complex clock
+settings (all HDMI rates).

+Subject: clk: qcom: msm8916: Fix the address location of pll->config_reg
+
+From: Bryan O'Donoghue <bryan.odonoghue@linaro.org>
+
+[ Upstream commit f47ab3c2f5338828a67e89d5f688d2cef9605245 ]
+
+During the process of debugging a processor derived from the msm8916 which
+we found the new processor was not starting one of its PLLs.
+
+After tracing the addresses and writes that downstream was doing and
+comparing to upstream it became obvious that we were writing to a different
+register location than downstream when trying to configure the PLL.
+
+This error is also present in upstream msm8916.
+
+As an example clk-pll.c::clk_pll_recalc_rate wants to write to
+pll->config_reg updating the bit-field POST_DIV_RATIO. That bit-field is
+defined in PLL_USER_CTL not in PLL_CONFIG_CTL. Taking the BIMC PLL as an
+example
+
+lm80-p0436-13_c_qc_snapdragon_410_processor_hrd.pdf
+
+0x01823010 GCC_BIMC_PLL_USER_CTL
+0x01823014 GCC_BIMC_PLL_CONFIG_CTL
+
+This pattern is repeated for gpll0, gpll1, gpll2 and bimc_pll.
+
+This error is likely not apparent since the bootloader will already have
+initialized these PLLs.
+
+This patch corrects the location of config_reg from PLL_CONFIG_CTL to
+PLL_USER_CTL for all relevant PLLs on msm8916.
+
+Fixes commit 3966fab8b6ab ("clk: qcom: Add MSM8916 Global Clock Controller support")

+[ Upstream commit ace342097768e35fd41934285604fa97da1e235a ]
+
+On SoCs with Standby Control Registers (STBCRs) instead of Module Stop
+Control Registers (MSTPCRs), the suspend handler saves the wrong
+registers, and the resume handler prints the wrong register in an error
+message.
+
+Fortunately this cannot happen yet, as the suspend/resume code is used
+on PSCI systems only, and systems with STBCRs (RZ/A1 and RZ/A2) do not
+use PSCI. Still, it is better to fix this, to avoid this becoming a
+problem in the future.
+
+Distinguish between STBCRs and MSTPCRs where needed. Replace the
+useless printing of the virtual register address in the resume error
+message by printing the register index.

+From: Marek Szyprowski <m.szyprowski@samsung.com>
+
+[ Upstream commit 25bdae0f1c6609ceaf55fe6700654f0be2253d8e ]
+
+Mark the SCLK clock for Exynos5433 I2S1 device with IGNORE_UNUSED flag to
+match its behaviour with SCLK clock for AUD_I2S (I2S0) device until
+a proper fix for Exynos I2S driver is ready.

+Subject: clk: samsung: Mark top ISP and CAM clocks on Exynos542x as critical
+
+From: Marek Szyprowski <m.szyprowski@samsung.com>
+
+[ Upstream commit e47bd937e602bb4379546095d1bd0b9871fa60c2 ]
+
+The TOP 'aclk*_isp', 'aclk550_cam', 'gscl_wa' and 'gscl_wb' clocks must
+be kept enabled all the time to allow proper access to power management
+control for the ISP and CAM power domains. The last two clocks, although
+related to GScaler device and GSCL power domain, provides also the
+I_WRAP_CLK signal to MIPI CSIS0/1 devices, which are a part of CAM power
+domain and are needed for proper power on/off sequence.
+
+Currently there are no drivers for the devices, which are part of CAM and
+ISP power domains yet. This patch only fixes the race between disabling
+the unused power domains and disabling unused clocks, which randomly
+resulted in the following error during boot:
+
+Power domain CAM disable failed
+Power domain ISP disable failed

+Subject: coresight: tmc: Fix TMC mode read in tmc_read_prepare_etb()
+
+From: Sai Prakash Ranjan <saiprakash.ranjan@codeaurora.org>
+
+[ Upstream commit 347adb0d6385c3220dc01ab61807a5b1892901cc ]
+
+On some QCOM platforms like SC7180, SDM845 and SM8150,
+reading TMC mode register without proper coresight power
+management can lead to async exceptions like the one in
+the call trace below in tmc_read_prepare_etb(). This can
+happen if the user tries to read the TMC etf data via
+device node without setting up source and the sink first.
+Fix this by having a check for coresight sysfs mode
+before reading TMC mode management register.

+Subject: crypto: omap-sham - add proper load balancing support for multicore
+
+From: Tero Kristo <t-kristo@ti.com>
+
+[ Upstream commit 281c377872ff5d15d80df25fc4df02d2676c7cde ]
+
+The current implementation of the multiple accelerator core support for
+OMAP SHA does not work properly. It always picks up the first probed
+accelerator core if this is available, and rest of the book keeping also
+gets confused if there are two cores available. Add proper load
+balancing support for SHA, and also fix any bugs related to the
+multicore support while doing it.

+Subject: /dev/mem: Revoke mappings when a driver claims the region
+
+From: Dan Williams <dan.j.williams@intel.com>
+
+[ Upstream commit 3234ac664a870e6ea69ae3a57d824cd7edbeacc5 ]
+
+Close the hole of holding a mapping over kernel driver takeover event of
+a given address range.
+
+Commit 90a545e98126 ("restrict /dev/mem to idle io memory ranges")
+introduced CONFIG_IO_STRICT_DEVMEM with the goal of protecting the
+kernel against scenarios where a /dev/mem user tramples memory that a
+kernel driver owns. However, this protection only prevents *new* read(),
+write() and mmap() requests. Established mappings prior to the driver
+calling request_mem_region() are left alone.
+
+Especially with persistent memory, and the core kernel metadata that is
+stored there, there are plentiful scenarios for a /dev/mem user to
+violate the expectations of the driver and cause amplified damage.
+
+Teach request_mem_region() to find and shoot down active /dev/mem
+mappings that it believes it has successfully claimed for the exclusive
+use of the driver. Effectively a driver call to request_mem_region()
+becomes a hole-punch on the /dev/mem device.
+
+The typical usage of unmap_mapping_range() is part of
+truncate_pagecache() to punch a hole in a file, but in this case the
+implementation is only doing the "first half" of a hole punch. Namely it
+is just evacuating current established mappings of the "hole", and it
+relies on the fact that /dev/mem establishes mappings in terms of
+absolute physical address offsets. Once existing mmap users are
+invalidated they can attempt to re-establish the mapping, or attempt to
+continue issuing read(2) / write(2) to the invalidated extent, but they
+will then be subject to the CONFIG_IO_STRICT_DEVMEM checking that can
+block those subsequent accesses.

+Subject: dlm: remove BUG() before panic()
+
+From: Arnd Bergmann <arnd@arndb.de>
+
+[ Upstream commit fe204591cc9480347af7d2d6029b24a62e449486 ]
+
+Building a kernel with clang sometimes fails with an objtool error in dlm:
+
+fs/dlm/lock.o: warning: objtool: revert_lock_pc()+0xbd: can't find jump dest instruction at .text+0xd7fc
+
+The problem is that BUG() never returns and the compiler knows
+that anything after it is unreachable, however the panic still
+emits some code that does not get fully eliminated.
+
+Having both BUG() and panic() is really pointless as the BUG()
+kills the current process and the subsequent panic() never hits.
+In most cases, we probably don't really want either and should
+replace the DLM_ASSERT() statements with WARN_ON(), as has
+been done for some of them.
+
+Remove the BUG() here so the user at least sees the panic message
+and we can reliably build randconfig kernels.

+Subject: dm mpath: switch paths in dm_blk_ioctl() code path
+
+From: Martin Wilck <mwilck@suse.com>
+
+[ Upstream commit 2361ae595352dec015d14292f1b539242d8446d6 ]
+
+SCSI LUN passthrough code such as qemu's "scsi-block" device model
+pass every IO to the host via SG_IO ioctls. Currently, dm-multipath
+calls choose_pgpath() only in the block IO code path, not in the ioctl
+code path (unless current_pgpath is NULL). This has the effect that no
+path switching and thus no load balancing is done for SCSI-passthrough
+IO, unless the active path fails.
+
+Fix this by using the same logic in multipath_prepare_ioctl() as in
+multipath_clone_and_map().
+
+Note: The allegedly best path selection algorithm, service-time,
+still wouldn't work perfectly, because the io size of the current
+request is always set to 0. Changing that for the IO passthrough
+case would require the ioctl cmd and arg to be passed to dm's
+prepare_ioctl() method.

+Subject: drivers: base: Fix NULL pointer exception in
+ __platform_driver_probe() if a driver developer is foolish
+
+From: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@linux.intel.com>
+
+[ Upstream commit 388bcc6ecc609fca1b4920de7dc3806c98ec535e ]
+
+If platform bus driver registration is failed then, accessing
+platform bus spin lock (&drv->driver.bus->p->klist_drivers.k_lock)
+in __platform_driver_probe() without verifying the return value
+__platform_driver_register() can lead to NULL pointer exception.
+
+So check the return value before attempting the spin lock.
+
+One such example is below:
+
+For a custom usecase, I have intentionally failed the platform bus
+registration and I expected all the platform device/driver
+registrations to fail gracefully. But I came across this panic
+issue.

+In L3C uncore PMU drivers, bit16 is used to control all counters enable &

+Subject: drm/amd/display: Revalidate bandwidth before commiting DC updates
+
+From: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com>
+
+[ Upstream commit a24eaa5c51255b344d5a321f1eeb3205f2775498 ]
+
+[Why]
+Whenever we switch between tiled formats without also switching pixel
+formats or doing anything else that recreates the DC plane state we
+can run into underflow or hangs since we're not updating the
+DML parameters before committing to the hardware.
+
+[How]
+If the update type is FULL then call validate_bandwidth again to update
+the DML parmeters before committing the state.
+
+This is basically just a workaround and protective measure against
+update types being added DC where we could run into this issue in
+the future.
+
+We can only fully validate the state in advance before applying it to
+the hardware if we recreate all the plane and stream states since
+we can't modify what's currently in use.
+
+The next step is to update DM to ensure that we're creating the plane
+and stream states for whatever could potentially be a full update in
+DC to pre-emptively recreate the state for DC global validation.
+
+The workaround can stay until this has been fixed in DM.

+Subject: f2fs: don't return vmalloc() memory from f2fs_kmalloc()
+
+From: Eric Biggers <ebiggers@google.com>
+
+[ Upstream commit 0b6d4ca04a86b9dababbb76e58d33c437e127b77 ]
+
+kmalloc() returns kmalloc'ed memory, and kvmalloc() returns either
+kmalloc'ed or vmalloc'ed memory. But the f2fs wrappers, f2fs_kmalloc()
+and f2fs_kvmalloc(), both return both kinds of memory.
+
+It's redundant to have two functions that do the same thing, and also
+breaking the standard naming convention is causing bugs since people
+assume it's safe to kfree() memory allocated by f2fs_kmalloc(). See
+e.g. the various allocations in fs/f2fs/compress.c.
+
+Fix this by making f2fs_kmalloc() just use kmalloc(). And to avoid
+re-introducing the allocation failures that the vmalloc fallback was
+intended to fix, convert the largest allocations to use f2fs_kvmalloc().

+Subject: firmware: qcom_scm: fix bogous abuse of dma-direct internals
+
+From: Christoph Hellwig <hch@lst.de>
+
+[ Upstream commit 459b1f86f1cba7de813fbc335df476c111feec22 ]
+
+As far as the device is concerned the dma address is the physical
+address. There is no need to convert it to a physical address,
+especially not using dma-direct internals that are not available
+to drivers and which will interact badly with IOMMUs. Last but not
+least the commit introducing it claimed to just fix a type issue,
+but actually changed behavior.

+Subject: geneve: change from tx_error to tx_dropped on missing metadata
+
+From: Jiri Benc <jbenc@redhat.com>
+
+[ Upstream commit 9d149045b3c0e44c049cdbce8a64e19415290017 ]
+
+If the geneve interface is in collect_md (external) mode, it can't send any
+packets submitted directly to its net interface, as such packets won't have
+metadata attached. This is expected.
+
+However, the kernel itself sends some packets to the interface, most
+notably, IPv6 DAD, IPv6 multicast listener reports, etc. This is not wrong,
+as tunnel metadata can be specified in routing table (although technically,
+that has never worked for IPv6, but hopefully will be fixed eventually) and
+then the interface must correctly participate in IPv6 housekeeping.
+
+The problem is that any such attempt increases the tx_error counter. Just
+bringing up a geneve interface with IPv6 enabled is enough to see a number
+of tx_errors. That causes confusion among users, prompting them to find
+a network error where there is none.
+
+Change the counter used to tx_dropped. That better conveys the meaning
+(there's nothing wrong going on, just some packets are getting dropped) and
+hopefully will make admins panic less.

+Subject: gfs2: Allow lock_nolock mount to specify jid=X
+
+From: Bob Peterson <rpeterso@redhat.com>
+
+[ Upstream commit ea22eee4e6027d8927099de344f7fff43c507ef9 ]
+
+Before this patch, a simple typo accidentally added \n to the jid=
+string for lock_nolock mounts. This made it impossible to mount a
+gfs2 file system with a journal other than journal0. Thus:
+
+mount -tgfs2 -o hostdata="jid=1" <device> <mount pt>
+
+Resulted in:
+mount: wrong fs type, bad option, bad superblock on <device>
+
+In most cases this is not a problem. However, for debugging and
+testing purposes we sometimes want to test the integrity of other
+journals. This patch removes the unnecessary \n and thus allows
+lock_nolock users to specify an alternate journal.

+Subject: gfs2: fix use-after-free on transaction ail lists
+
+From: Bob Peterson <rpeterso@redhat.com>
+
+[ Upstream commit 83d060ca8d90fa1e3feac227f995c013100862d3 ]
+
+Before this patch, transactions could be merged into the system
+transaction by function gfs2_merge_trans(), but the transaction ail
+lists were never merged. Because the ail flushing mechanism can run
+separately, bd elements can be attached to the transaction's buffer
+list during the transaction (trans_add_meta, etc) but quickly moved
+to its ail lists. Later, in function gfs2_trans_end, the transaction
+can be freed (by gfs2_trans_end) while it still has bd elements
+queued to its ail lists, which can cause it to either lose track of
+the bd elements altogether (memory leak) or worse, reference the bd
+elements after the parent transaction has been freed.
+
+Although I've not seen any serious consequences, the problem becomes
+apparent with the previous patch's addition of:
+
+ gfs2_assert_warn(sdp, list_empty(&tr->tr_ail1_list));
+
+to function gfs2_trans_free().
+
+This patch adds logic into gfs2_merge_trans() to move the merged
+transaction's ail lists to the sdp transaction. This prevents the
+use-after-free. To do this properly, we need to hold the ail lock,
+so we pass sdp into the function instead of the transaction itself.

+Subject: gpio: pca953x: fix handling of automatic address incrementing
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
+
+[ Upstream commit bcf41dc480b179bfb669a232080a2e26dc7294b4 ]
+
+Some of the chips supported by the pca953x driver need the most
+significant bit in the address word set to automatically increment the
+address pointer on subsequent reads and writes (example: PCA9505). With
+this bit unset the same register is read multiple times on a multi-byte
+read sequence. Other chips must not have this bit set and autoincrement
+always (example: PCA9555).
+
+Up to now this AI bit was interpreted to be part of the address, which
+resulted in inconsistent regmap caching when a register was written with
+AI set and then read without it. This happened for the PCA9505 in
+pca953x_gpio_set_multiple() where pca953x_read_regs() bulk read from the
+cache for registers 0x8-0xc and then wrote to registers 0x88-0x8c. (Side
+note: reading 5 values from offset 0x8 yiels OP0 5 times because AI must
+be set to get OP0-OP4, which is another bug that is resolved here as a
+by-product.) The same problem happens when calls to gpio_set_value() and
+gpio_set_array_value() were mixed.
+
+With this patch the AI bit is always set for chips that support it. This
+works as there are no code locations that make use of the behaviour with
+AI unset (for the chips that support it).
+
+Note that the call to pca953x_setup_gpio() had to be done a bit earlier
+to make the NBANK macro work.
+
+The history of this bug is a bit complicated. Commit b32cecb46bdc
+("gpio: pca953x: Extract the register address mangling to single
+function") changed which chips and functions are affected. Commit
+3b00691cc46a ("gpio: pca953x: hack to fix 24 bit gpio expanders") used
+some duct tape to make the driver at least appear to work. Commit
+49427232764d ("gpio: pca953x: Perform basic regmap conversion")
+introduced the caching. Commit b4818afeacbd ("gpio: pca953x: Add
+set_multiple to allow multiple bits to be set in one write.") introduced
+the .set_multiple() callback which didn't work for chips that need the
+AI bit which was fixed later for some chips in 8958262af3fb ("gpio:
+pca953x: Repair multi-byte IO address increment on PCA9575"). So I'm
+sorry, I don't know which commit I should pick for a Fixes: line.

+Subject: habanalabs: increase timeout during reset
+
+From: Oded Gabbay <oded.gabbay@gmail.com>
+
+[ Upstream commit 7a65ee046b2238e053f6ebb610e1a082cfc49490 ]
+
+When doing training, the DL framework (e.g. tensorflow) performs hundreds
+of thousands of memory allocations and mappings. In case the driver needs
+to perform hard-reset during training, the driver kills the application and
+unmaps all those memory allocations. Unfortunately, because of that large
+amount of mappings, the driver isn't able to do that in the current timeout
+(5 seconds). Therefore, increase the timeout significantly to 30 seconds
+to avoid situation where the driver resets the device with active mappings,
+which sometime can cause a kernel bug.
+
+BTW, it doesn't mean we will spend all the 30 seconds because the reset
+thread checks every one second if the unmap operation is done.

+Subject: i2c: piix4: Detect secondary SMBus controller on AMD AM4 chipsets
+
+From: Adam Honse <calcprogrammer1@gmail.com>
+
+[ Upstream commit f27237c174fd9653033330e4e532cd9d153ce824 ]
+
+The AMD X370 and other AM4 chipsets (A/B/X 3/4/5 parts) and Threadripper
+equivalents have a secondary SMBus controller at I/O port address
+0x0B20. This bus is used by several manufacturers to control
+motherboard RGB lighting via embedded controllers. I have been using
+this bus in my OpenRGB project to control the Aura RGB on many
+motherboards and ASRock also uses this bus for their Polychrome RGB
+controller.
+
+I am not aware of any CZ-compatible platforms which do not have the
+second SMBus channel. All of AMD's AM4- and Threadripper- series
+chipsets that OpenRGB users have tested appear to have this secondary
+bus. I also noticed this secondary bus is present on older AMD
+platforms including my FM1 home server.

+From: Russell King <rmk+kernel@armlinux.org.uk>
+
+[ Upstream commit e81c979f4e071d516aa27cf5a0c3939da00dc1ca ]
+
+If we timeout during a message transfer, the control register may
+contain bits that cause an action to be set. Read-modify-writing the
+register leaving these bits set may trigger the hardware to attempt
+one of these actions unintentionally.
+
+Always clear these bits when cleaning up after a message or after
+a timeout.

+Subject: i2c: pxa: fix i2c_pxa_scream_blue_murder() debug output
+
+From: Russell King <rmk+kernel@armlinux.org.uk>
+
+[ Upstream commit 88b73ee7ca4c90baf136ed5a8377fc5a9b73ac08 ]
+
+The IRQ log output is supposed to appear on a single line. However,
+commit 3a2dc1677b60 ("i2c: pxa: Update debug function to dump more info
+on error") resulted in it being printed one-entry-per-line, which is
+excessively long.
+
+Fixing this is not a trivial matter; using pr_cont() doesn't work as
+the previous dev_dbg() may not have been compiled in, or may be
+dynamic.
+
+Since the rest of this function output is at error level, and is also
+debug output, promote this to error level as well to avoid this
+problem.
+
+Reduce the number of always zero prefix digits to save screen real-
+estate.

+Subject: iavf: fix speed reporting over virtchnl
+
+From: Brett Creeley <brett.creeley@intel.com>
+
+[ Upstream commit e0ef26fbe2b0c62f42ba7667076dc38b693b6fb8 ]
+
+Link speeds are communicated over virtchnl using an enum
+virtchnl_link_speed. Currently, the highest link speed is 40Gbps which
+leaves us unable to reflect some speeds that an ice VF is capable of.
+This causes link speed to be misreported on the iavf driver.
+
+Allow for communicating link speeds using Mbps so that the proper speed can
+be reported for an ice VF. Moving away from the enum allows us to
+communicate future speed changes without requiring a new enum to be added.
+
+In order to support communicating link speeds over virtchnl in Mbps the
+following functionality was added:
+ - Added u32 link_speed_mbps in the iavf_adapter structure.
+ - Added the macro ADV_LINK_SUPPORT(_a) to determine if the VF
+ driver supports communicating link speeds in Mbps.
+ - Added the function iavf_get_vpe_link_status() to fill the
+ correct link_status in the event_data union based on the
+ ADV_LINK_SUPPORT(_a) macro.
+ - Added the function iavf_set_adapter_link_speed_from_vpe()
+ to determine whether or not to fill the u32 link_speed_mbps or
+ enum virtchnl_link_speed link_speed field in the iavf_adapter
+ structure based on the ADV_LINK_SUPPORT(_a) macro.
+ - Do not free vf_res in iavf_init_get_resources() as vf_res will be
+ accessed in iavf_get_link_ksettings(); memset to 0 instead. This
+ memory is subsequently freed in iavf_remove().
+

+
+From: Maor Gottlieb <maorg@mellanox.com>
+
+[ Upstream commit 63a3345c2d42a9b29e1ce2d3a4043689b3995cea ]
+
+The allocated ports structure in never freed. The free function should be
+called by release_cma_ports_group, but the group is never released since
+we don't remove its default group.
+
+Remove default groups when device group is deleted.

+Subject: iio: bmp280: fix compensation of humidity
+
+From: Andreas Klinger <ak@it-klinger.de>
+
+[ Upstream commit dee2dabc0e4115b80945fe2c91603e634f4b4686 ]
+
+Limit the output of humidity compensation to the range between 0 and 100
+percent.
+
+Depending on the calibration parameters of the individual sensor it
+happens, that a humidity above 100 percent or below 0 percent is
+calculated, which don't make sense in terms of relative humidity.
+
+Add a clamp to the compensation formula as described in the datasheet of
+the sensor in chapter 4.2.3.
+
+Although this clamp is documented, it was never in the driver of the
+kernel.
+
+It depends on the circumstances (calibration parameters, temperature,
+humidity) if one can see a value above 100 percent without the clamp.
+The writer of this patch was working with this type of sensor without
+noting this error. So it seems to be a rare event when this bug occures.

+From: Arnd Bergmann <arnd@arndb.de>
+
+[ Upstream commit bd93f003b7462ae39a43c531abca37fe7073b866 ]
+
+Clang normally does not warn about certain issues in inline functions when
+it only happens in an eliminated code path. However if something else
+goes wrong, it does tend to complain about the definition of hweight_long()
+on 32-bit targets:
+
+ include/linux/bitops.h:75:41: error: shift count >= width of type [-Werror,-Wshift-count-overflow]
+ return sizeof(w) == 4 ? hweight32(w) : hweight64(w);

+ include/asm-generic/bitops/const_hweight.h:12:9: note: expanded from macro '__const_hweight8'
+ (!!((w) & (1ULL << 2))) + \
+
+Adding an explicit cast to __u64 avoids that warning and makes it easier
+to read other output.

+
+MMS345L is another first generation touch screen from Melfas,
+which uses mostly the same registers as MMS152.
+
+However, there is some garbage printed during initialization.
+Apparently MMS345L does not have the MMS152_COMPAT_GROUP register
+that is read+printed during initialization.
+
+ TSP FW Rev: bootloader 0x6 / core 0x26 / config 0x26, Compat group: \x06
+
+On earlier kernel versions the compat group was actually printed as
+an ASCII control character, seems like it gets escaped now.
+
+But we probably shouldn't print something from a random register.
+
+Add a separate "melfas,mms345l" compatible that avoids reading
+from the MMS152_COMPAT_GROUP register. This might also help in case
+there is some other device-specific quirk in the future.

+Subject: lib/zlib: remove outdated and incorrect pre-increment optimization
+
+From: Jann Horn <jannh@google.com>
+
+[ Upstream commit acaab7335bd6f0c0b54ce3a00bd7f18222ce0f5f ]
+
+The zlib inflate code has an old micro-optimization based on the
+assumption that for pre-increment memory accesses, the compiler will
+generate code that fits better into the processor's pipeline than what
+would be generated for post-increment memory accesses.
+
+This optimization was already removed in upstream zlib in 2016:
+https://github.com/madler/zlib/commit/9aaec95e8211
+
+This optimization causes UB according to C99, which says in section 6.5.6
+"Additive operators": "If both the pointer operand and the result point to
+elements of the same array object, or one past the last element of the
+array object, the evaluation shall not produce an overflow; otherwise, the
+behavior is undefined".
+
+This UB is not only a theoretical concern, but can also cause trouble for
+future work on compiler-based sanitizers.
+
+According to the zlib commit, this optimization also is not optimal
+anymore with modern compilers.
+
+Replace uses of OFF, PUP and UP_UNALIGNED with their definitions in the
+POSTINC case, and remove the macro definitions, just like in the upstream
+patch.

+Subject: libata: Use per port sync for detach
+
+From: Kai-Heng Feng <kai.heng.feng@canonical.com>
+
+[ Upstream commit b5292111de9bb70cba3489075970889765302136 ]
+
+Commit 130f4caf145c ("libata: Ensure ata_port probe has completed before
+detach") may cause system freeze during suspend.
+
+Using async_synchronize_full() in PM callbacks is wrong, since async
+callbacks that are already scheduled may wait for not-yet-scheduled
+callbacks, causes a circular dependency.
+
+Instead of using big hammer like async_synchronize_full(), use async
+cookie to make sure port probe are synced, without affecting other
+scheduled PM callbacks.

+Subject: libbpf: Handle GCC noreturn-turned-volatile quirk
+
+From: Andrii Nakryiko <andriin@fb.com>
+
+[ Upstream commit 32022fd97ed34f6812802bf1288db27c313576f4 ]
+
+Handle a GCC quirk of emitting extra volatile modifier in DWARF (and
+subsequently preserved in BTF by pahole) for function pointers marked as
+__attribute__((noreturn)). This was the way to mark such functions before GCC
+2.5 added noreturn attribute. Drop such func_proto modifiers, similarly to how
+it's done for array (also to handle GCC quirk/bug).
+
+Such volatile attribute is emitted by GCC only, so existing selftests can't
+express such test. Simple repro is like this (compiled with GCC + BTF
+generated by pahole):
+
+ struct my_struct {
+ void __attribute__((noreturn)) (*fn)(int);
+ };
+ struct my_struct a;
+
+Without this fix, output will be:
+
+struct my_struct {
+ voidvolatile (*fn)(int);
+};
+
+With the fix:
+
+struct my_struct {
+ void (*fn)(int);
+};

+
+From: Amelie Delaunay <amelie.delaunay@st.com>

+[ Upstream commit 97eda5dcc2cde5dcc778bef7a9344db3b6bf8ef5 ]
+
+When STMFX supply is stopped, spurious interrupt can occur. To avoid that,
+disable the interrupt in suspend before disabling the regulator and

+From: Marek Szyprowski <m.szyprowski@samsung.com>
+
+[ Upstream commit d4f9b5428b53dd67f49ee8deed8d4366ed6b1933 ]
+
+WM8994 chip has built-in regulators, which might be used for chip
+operation. They are controlled by a separate wm8994-regulator driver,
+which should be loaded before this driver calls regulator_get(), because
+that driver also provides consumer-supply mapping for the them. If that
+driver is not yet loaded, regulator core substitute them with dummy
+regulator, what breaks chip operation, because the built-in regulators are
+never enabled. Fix this by annotating this driver with MODULE_SOFTDEP()
+"pre" dependency to "wm8994_regulator" module.

+
+From: John Hubbard <jhubbard@nvidia.com>
+
+[ Upstream commit 57343d51613227373759f5b0f2eede257fd4b82e ]
+
+This fixes the case of get_user_pages_fast() returning a -errno.
+The result needs to be stored in a signed integer. And for safe
+signed/unsigned comparisons, it's best to keep everything signed.
+And get_user_pages_fast() also expects a signed value for number
+of pages to pin.
+
+Therefore, change most relevant variables, from u32 to int. Leave
+"n" unsigned, for convenience in checking for overflow. And provide
+a WARN_ON_ONCE() and early return, if overflow occurs.
+
+Also, as long as we're tidying up: rename the page array from page,
+to pages, in order to match the conventions used in most other call
+sites.

+From: ashimida <ashimida@linux.alibaba.com>
+
+[ Upstream commit 72d24accf02add25e08733f0ecc93cf10fcbd88c ]
+
+When System.map was generated, the kernel used mksysmap to
+filter the kernel symbols, but all the symbols with the
+second letter 'L' in the kernel were filtered out, not just
+the symbols starting with 'dot + L'.
+
+For example:
+ashimida@ubuntu:~/linux$ cat System.map |grep ' .L'
+ashimida@ubuntu:~/linux$ nm -n vmlinux |grep ' .L'
+ffff0000088028e0 t bLength_show
+......
+ffff0000092e0408 b PLLP_OUTC_lock
+ffff0000092e0410 b PLLP_OUTA_lock
+
+The original intent should be to filter out all local symbols
+starting with '.L', so the dot should be escaped.

+Subject: net: dsa: lantiq_gswip: fix and improve the unsupported interface
+ error
+
+From: Martin Blumenstingl <martin.blumenstingl@googlemail.com>
+
+[ Upstream commit 4d3da2d8d91f66988a829a18a0ce59945e8ae4fb ]
+
+While trying to use the lantiq_gswip driver on one of my boards I made
+a mistake when specifying the phy-mode (because the out-of-tree driver
+wants phy-mode "gmii" or "mii" for the internal PHYs). In this case the
+following error is printed multiple times:
+ Unsupported interface: 3
+
+While it gives at least a hint at what may be wrong it is not very user
+friendly. Print the human readable phy-mode and also which port is
+configured incorrectly (this hardware supports ports 0..6) to improve
+the cases where someone made a mistake.

+Subject: net/filter: Permit reading NET in load_bytes_relative when MAC not
+ set
+
+From: YiFei Zhu <zhuyifei1999@gmail.com>
+
+[ Upstream commit 0f5d82f187e1beda3fe7295dfc500af266a5bd80 ]
+
+Added a check in the switch case on start_header that checks for
+the existence of the header, and in the case that MAC is not set
+and the caller requests for MAC, -EFAULT. If the caller requests
+for NET then MAC's existence is completely ignored.
+
+There is no function to check NET header's existence and as far
+as cgroup_skb/egress is concerned it should always be set.
+
+Removed for ptr >= the start of header, considering offset is
+bounded unsigned and should always be true. len <= end - mac is
+redundant to ptr + len <= end.

+[ Upstream commit 118917d696dc59fd3e1741012c2f9db2294bed6f ]
+
+Fix off-by-one issues in 'rpc_ntop6':
+ - 'snprintf' returns the number of characters which would have been
+ written if enough space had been available, excluding the terminating
+ null byte. Thus, a return value of 'sizeof(scopebuf)' means that the
+ last character was dropped.
+ - 'strcat' adds a terminating null byte to the string, thus if len ==
+ buflen, the null byte is written past the end of the buffer.

+Subject: nfs: set invalid blocks after NFSv4 writes
+
+From: Zheng Bin <zhengbin13@huawei.com>
+
+[ Upstream commit 3a39e778690500066b31fe982d18e2e394d3bce2 ]
+
+Use the following command to test nfsv4(size of file1M is 1MB):
+mount -t nfs -o vers=4.0,actimeo=60 127.0.0.1/dir1 /mnt
+cp file1M /mnt
+du -h /mnt/file1M -->0 within 60s, then 1M
+
+When write is done(cp file1M /mnt), will call this:
+nfs_writeback_done
+ nfs4_write_done
+ nfs4_write_done_cb
+ nfs_writeback_update_inode
+ nfs_post_op_update_inode_force_wcc_locked(change, ctime, mtime
+nfs_post_op_update_inode_force_wcc_locked
+ nfs_set_cache_invalid
+ nfs_refresh_inode_locked
+ nfs_update_inode
+
+nfsd write response contains change, ctime, mtime, the flag will be
+clear after nfs_update_inode. Howerver, write response does not contain
+space_used, previous open response contains space_used whose value is 0,
+so inode->i_blocks is still 0.
+
+nfs_getattr -->called by "du -h"
+ do_update |= force_sync || nfs_attribute_cache_expired -->false in 60s
+ cache_validity = READ_ONCE(NFS_I(inode)->cache_validity)
+ do_update |= cache_validity & (NFS_INO_INVALID_ATTR -->false
+ if (do_update) {
+ __nfs_revalidate_inode
+ }
+
+Within 60s, does not send getattr request to nfsd, thus "du -h /mnt/file1M"
+is 0.
+
+Add a NFS_INO_INVALID_BLOCKS flag, set it when nfsv4 write is done.

+
+[ Upstream commit a4abc6b12eb1f7a533c2e7484cfa555454ff0977 ]
+
+nfsd4_process_cb_update() invokes svc_xprt_get(), which increases the
+refcount of the "c->cn_xprt".
+
+The reference counting issue happens in one exception handling path of
+nfsd4_process_cb_update(). When setup callback client failed, the
+function forgets to decrease the refcnt increased by svc_xprt_get(),
+causing a refcnt leak.
+
+Fix this issue by calling svc_xprt_put() when setup callback client
+failed.

+Subject: NTB: Fix the default port and peer numbers for legacy drivers
+
+From: Logan Gunthorpe <logang@deltatee.com>
+
+[ Upstream commit fc8b086d9dbd57458d136c4fa70ee26f832c3a2e ]
+
+When the commit adding ntb_default_port_number() and
+ntb_default_peer_port_number() entered the kernel there was no
+users of it so it was impossible to tell what the API needed.
+
+When a user finally landed a year later (ntb_pingpong) there were
+more NTB topologies were created and no consideration was considered
+to how other drivers had changed.
+
+Now that there is a user it can be fixed to provide a sensible default
+for the legacy drivers that do not implement ntb_{peer_}port_number().
+Seeing ntb_pingpong doesn't check error codes returning EINVAL was also
+not sensible.
+
+Patches for ntb_pingpong and ntb_perf follow (which are broken
+otherwise) to support hardware that doesn't have port numbers. This is
+important not only to not break support with existing drivers but for
+the cross link topology which, due to its perfect symmetry, cannot
+assign unique port numbers to each side.

+
+From: Logan Gunthorpe <logang@deltatee.com>
+
+[ Upstream commit ca93c45755da98302c93abdd788fc09113baf9e0 ]
+
+This commit fixes pingpong support for existing drivers that do not
+implement ntb_default_port_number() and ntb_default_peer_port_number().
+This is required for hardware (like the crosslink topology of
+switchtec) which cannot assign reasonable port numbers to each port due
+to its perfect symmetry.
+
+Instead of picking the doorbell to use based on the the index of the
+peer, we use the peer's port number. This is a bit clearer and easier
+to understand.

+Subject: NTB: perf: Fix race condition when run with ntb_test
+
+From: Logan Gunthorpe <logang@deltatee.com>
+
+[ Upstream commit 34d8673a01b053b6231a995a4eec9341163d63be ]
+
+When running ntb_test, the script tries to run the ntb_perf test
+immediately after probing the modules. Since adding multi-port support,
+this fails seeing the new initialization procedure in ntb_perf
+can not complete instantly.
+
+To fix this we add a completion which is waited on when a test is
+started. In this way, run can be written any time after the module is
+loaded and it will wait for the initialization to complete instead of
+sending an error.

+Subject: NTB: perf: Fix support for hardware that doesn't have port numbers

+From: Logan Gunthorpe <logang@deltatee.com>
+
+[ Upstream commit b54369a248c2e033bfcf5d6917e08cf9d73d54a6 ]
+
+Legacy drivers do not have port numbers (but is reliably only two ports)
+and was broken by the recent commit that added mult-port support to
+ntb_perf. This is especially important to support the cross link
+topology which is perfectly symmetric and cannot assign unique port
+numbers easily.
+
+Hardware that returns zero for both the local port and the peer should
+just always use gidx=0 for the only peer.

+Change the tools back to using the PCI device for allocations seeing

+
+[ Upstream commit 6bd140e14d9aaa734ec37985b8b20a96c0ece948 ]
+
+Working on the OpenRISC glibc port I found that sometimes clone was
+working strange. That the tls data argument sent in r7 was always
+wrong. Further investigation revealed that the arguments were getting
+clobbered in the entry code. This patch removes the code that writes to
+the argument registers. This was likely due to some old code hanging
+around.
+
+This patch fixes this up for clone and fork. This fork clobber is
+harmless but also useless so remove.

+
+From: Miklos Szeredi <mszeredi@redhat.com>
+
+[ Upstream commit 56230d956739b9cb1cbde439d76227d77979a04d ]
+
+Check permission before opening a real file.
+
+ovl_path_open() is used by readdir and copy-up routines.
+
+ovl_permission() theoretically already checked copy up permissions, but it
+doesn't hurt to re-do these checks during the actual copy-up.
+
+For directory reading ovl_permission() only checks access to topmost
+underlying layer. Readdir on a merged directory accesses layers below the
+topmost one as well. Permission wasn't checked for these layers.
+
+Note: modifying ovl_permission() to perform this check would be far more
+complex and hence more bug prone. The result is less precise permissions
+returned in access(2). If this turns out to be an issue, we can revisit
+this bug.

+Subject: PCI: aardvark: Don't blindly enable ASPM L0s and don't write to
+ read-only register
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+
+[ Upstream commit 90c6cb4a355e7befcb557d217d1d8b8bd5875a05 ]
+
+Trying to change Link Status register does not have any effect as this
+is a read-only register. Trying to overwrite bits for Negotiated Link
+Width does not make sense.
+
+In future proper change of link width can be done via Lane Count Select
+bits in PCIe Control 0 register.
+
+Trying to unconditionally enable ASPM L0s via ASPM Control bits in Link
+Control register is wrong. There should be at least some detection if
+endpoint supports L0s as isn't mandatory.
+
+Moreover ASPM Control bits in Link Control register are controlled by
+pcie/aspm.c code which sets it according to system ASPM settings,
+immediately after aardvark driver probes. So setting these bits by
+aardvark driver has no long running effect.
+
+Remove code which touches ASPM L0s bits from this driver and let
+kernel's ASPM implementation to set ASPM state properly.
+
+Some users are reporting issues that this code is problematic for some
+Intel wifi cards and removing it fixes them, see e.g.:
+https://bugzilla.kernel.org/show_bug.cgi?id=196339
+
+If problems with Intel wifi cards occur even after this commit, then
+pcie/aspm.c code could be modified / hooked to not enable ASPM L0s state
+for affected problematic cards.

+Subject: PCI: Allow pci_resize_resource() for devices on root bus
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Ard Biesheuvel <ardb@kernel.org>
+
+[ Upstream commit d09ddd8190fbdc07696bf34b548ae15aa1816714 ]
+
+When resizing a BAR, pci_reassign_bridge_resources() is invoked to bring
+the bridge windows of parent bridges in line with the new BAR assignment.
+
+This assumes the device whose BAR is being resized lives on a subordinate
+bus, but this is not necessarily the case. A device may live on the root
+bus, in which case dev->bus->self is NULL, and passing a NULL pci_dev
+pointer to pci_reassign_bridge_resources() will cause it to crash.
+
+So let's make the call to pci_reassign_bridge_resources() conditional on
+whether dev->bus->self is non-NULL in the first place.

+Subject: PCI: amlogic: meson: Don't use FAST_LINK_MODE to set up link
+
+From: Marc Zyngier <maz@kernel.org>
+
+[ Upstream commit 87dccf09323fc363bd0d072fcc12b96622ab8c69 ]
+
+The vim3l board does not work with a standard PCIe switch (ASM1184e),
+spitting all kind of errors - hinting at HW misconfiguration (no link,
+port enumeration issues, etc).
+
+According to the the Synopsys DWC PCIe Reference Manual, in the section
+dedicated to the PLCR register, bit 7 is described (FAST_LINK_MODE) as:
+
+"Sets all internal timers to fast mode for simulation purposes."
+
+it is sound to set this bit from a simulation perspective, but on actual
+silicon, which expects timers to have a nominal value, it is not.
+
+Make sure the FAST_LINK_MODE bit is cleared when configuring the RC
+to solve this problem.

+
+From: Kai-Heng Feng <kai.heng.feng@canonical.com>
+
+[ Upstream commit 66ff14e59e8a30690755b08bc3042359703fb07a ]
+
+7d715a6c1ae5 ("PCI: add PCI Express ASPM support") added the ability for
+Linux to enable ASPM, but for some undocumented reason, it didn't enable
+ASPM on links where the downstream component is a PCIe-to-PCI/PCI-X Bridge.
+
+Remove this exclusion so we can enable ASPM on these links.
+
+The Dell OptiPlex 7080 mentioned in the bugzilla has a TI XIO2001
+PCIe-to-PCI Bridge. Enabling ASPM on the link leading to it allows the
+Intel SoC to enter deeper Package C-states, which is a significant power
+savings.

+
+From: Marc Zyngier <maz@kernel.org>
+
+[ Upstream commit 0414b93e78d87ecc24ae1a7e61fe97deb29fa2f4 ]
+
+On a system that uses the internal DWC MSI widget, I get this
+warning from debugfs when CONFIG_GENERIC_IRQ_DEBUGFS is selected:
+
+ debugfs: File ':soc:pcie@fc000000' in directory 'domains' already present!
+
+This is due to the fact that the DWC MSI code tries to register two
+IRQ domains for the same firmware node, without telling the low
+level code how to distinguish them (by setting a bus token). This
+further confuses debugfs which tries to create corresponding
+files for each domain.
+
+Fix it by tagging the inner domain as DOMAIN_BUS_NEXUS, which is
+the closest thing we have as to "generic MSI".

+Subject: PCI/PM: Assume ports without DLL Link Active train links in 100 ms
+
+From: Mika Westerberg <mika.westerberg@linux.intel.com>
+
+[ Upstream commit ec411e02b7a2e785a4ed9ed283207cd14f48699d ]
+
+Kai-Heng Feng reported that it takes a long time (> 1 s) to resume
+Thunderbolt-connected devices from both runtime suspend and system sleep
+(s2idle).
+
+This was because some Downstream Ports that support > 5 GT/s do not also
+support Data Link Layer Link Active reporting. Per PCIe r5.0 sec 6.6.1:
+
+ With a Downstream Port that supports Link speeds greater than 5.0 GT/s,
+ software must wait a minimum of 100 ms after Link training completes
+ before sending a Configuration Request to the device immediately below
+ that Port. Software can determine when Link training completes by polling
+ the Data Link Layer Link Active bit or by setting up an associated
+ interrupt (see Section 6.7.3.3).
+
+Sec 7.5.3.6 requires such Ports to support DLL Link Active reporting, but
+at least the Intel JHL6240 Thunderbolt 3 Bridge [8086:15c0] and the Intel
+JHL7540 Thunderbolt 3 Bridge [8086:15ea] do not.
+
+Previously we tried to wait for Link training to complete, but since there
+was no DLL Link Active reporting, all we could do was wait the worst-case
+1000 ms, then another 100 ms.
+
+Instead of using the supported speeds to determine whether to wait for Link
+training, check whether the port supports DLL Link Active reporting. The
+Ports in question do not, so we'll wait only the 100 ms required for Ports
+that support Link speeds <= 5 GT/s.
+
+This of course assumes these Ports always train the Link within 100 ms even
+if they are operating at > 5 GT/s, which is not required by the spec.

+Subject: PCI/PTM: Inherit Switch Downstream Port PTM settings from Upstream
+ Port
+
+From: Bjorn Helgaas <bhelgaas@google.com>
+
+[ Upstream commit 7b38fd9760f51cc83d80eed2cfbde8b5ead9e93a ]
+
+Except for Endpoints, we enable PTM at enumeration-time. Previously we did
+not account for the fact that Switch Downstream Ports are not permitted to
+have a PTM capability; their PTM behavior is controlled by the Upstream
+Port (PCIe r5.0, sec 7.9.16). Since Downstream Ports don't have a PTM
+capability, we did not mark them as "ptm_enabled", which meant that
+pci_enable_ptm() on an Endpoint failed because there was no PTM path to it.
+
+Mark Downstream Ports as "ptm_enabled" if their Upstream Port has PTM
+enabled.

+Subject: PCI: rcar: Fix incorrect programming of OB windows
+
+From: Andrew Murray <andrew.murray@arm.com>
+
+[ Upstream commit 2b9f217433e31d125fb697ca7974d3de3ecc3e92 ]
+
+The outbound windows (PCIEPAUR(x), PCIEPALR(x)) describe a mapping between
+a CPU address (which is determined by the window number 'x') and a
+programmed PCI address - Thus allowing the controller to translate CPU
+accesses into PCI accesses.
+
+However the existing code incorrectly writes the CPU address - lets fix
+this by writing the PCI address instead.
+
+For memory transactions, existing DT users describe a 1:1 identity mapping
+and thus this change should have no effect. However the same isn't true for
+I/O.

+Subject: PCI: vmd: Filter resource type bits from shadow register
+
+From: Jon Derrick <jonathan.derrick@intel.com>
+
+[ Upstream commit 3e5095eebe015d5a4d566aa5e03c8621add5f0a7 ]
+
+Versions of VMD with the Host Physical Address shadow register use this
+register to calculate the bus address offset needed to do guest
+passthrough of the domain. This register shadows the Host Physical
+Address registers including the resource type bits. After calculating
+the offset, the extra resource type bits lead to the VMD resources being
+over-provisioned at the front and under-provisioned at the back.
+
+Example:
+pci 10000:80:02.0: reg 0x10: [mem 0xf801fffc-0xf803fffb 64bit]
+
+Expected:
+pci 10000:80:02.0: reg 0x10: [mem 0xf8020000-0xf803ffff 64bit]
+
+If other devices are mapped in the over-provisioned front, it could lead
+to resource conflict issues with VMD or those devices.

+
+[ Upstream commit 0b47afc65453a70bc521e251138418056f65793f ]
+
+This fixes a problem with using the GPIO as an interrupt on Jaguar2
+(and similar), as the register layout of the platforms with 64 GPIO's
+are pairwise, such that the original offset must be multiplied with
+the platform stride.

+From: Dafna Hirschfeld <dafna.hirschfeld@collabora.com>
+
+[ Upstream commit d7faa8ffb6be57bf8233a4b5a636d76b83c51ce7 ]

+In function rockchip_dt_node_to_map, a new_map variable is
+allocated by:
+
+new_map = devm_kcalloc(pctldev->dev, map_num, sizeof(*new_map),
+ GFP_KERNEL);
+
+This uses devres and attaches new_map to the pinctrl driver.
+This cause a leak since new_map is not released when the probed
+driver is removed. Fix it by using kcalloc to allocate new_map
+and free it in `rockchip_dt_free_map`

+
+Mapping RO data as ROX is not an issue since that data
+cannot be modified to introduce an exploit.
+
+PPC64 accepts to have RO data mapped ROX, as a trade off
+between kernel size and strictness of protection.
+
+On PPC32, kernel size is even more critical as amount of
+memory is usually small.
+
+Depending on the number of available IBATs, the last IBATs
+might overflow the end of text. Only warn if it crosses
+the end of RO data.

+

+ ...
+ WARN_ON((usermsr & MSR_VSX) && !((usermsr & MSR_FP) && (usermsr & MSR_VEC)));

+
+This looks suspiciously like stack frames, not a pt_regs. If we look
+closely we can see return addresses from the stack trace above,
+c000000002004820 (start_kernel) and c00000000000c49c (start_here_common).
+
+init_task->thread.regs is setup at build time in processor.h:
+
+ #define INIT_THREAD { \
+ .ksp = INIT_SP, \
+ .regs = (struct pt_regs *)INIT_SP - 1, /* XXX bogus, I think */ \
+
+The early boot code where we setup the initial stack is:
+
+ LOAD_REG_ADDR(r3,init_thread_union)
+
+ /* set up a stack pointer */
+ LOAD_REG_IMMEDIATE(r1,THREAD_SIZE)
+ add r1,r3,r1
+ li r0,0
+ stdu r0,-STACK_FRAME_OVERHEAD(r1)
+
+Which creates a stack frame of size 112 bytes (STACK_FRAME_OVERHEAD).
+Which is far too small to contain a pt_regs.
+
+So the result is init_task->thread.regs is pointing at some stack
+frames on the init stack, not at a pt_regs.
+
+We have gotten away with this for so long because with pt_regs at its
+current size the MSR happens to point into the first frame, at a
+location that is not written to by the early asm. With the 16 byte
+expansion the MSR falls into the second frame, which is used by the
+compiler, and collides with a saved register that tends to be
+non-zero.
+
+As far as I can see this has been wrong since the original merge of
+64-bit ppc support, back in 2002.
+
+Conceptually swapper should have no regs, it never entered from
+userspace, and in fact that's what we do on 32-bit. It's also
+presumably what the "bogus" comment is referring to.
+
+So I think the right fix is to just not-initialise regs at all. I'm
+slightly worried this will break some code that isn't prepared for a
+NULL regs, but we'll have to see.
+
+Remove the comment in head_64.S which refers to us setting up the
+regs (even though we never did), and is otherwise not really accurate
+any more.

+Subject: powerpc/64s/exception: Fix machine check no-loss idle wakeup
+
+From: Nicholas Piggin <npiggin@gmail.com>
+
+[ Upstream commit 8a5054d8cbbe03c68dcb0957c291c942132e4101 ]
+
+The architecture allows for machine check exceptions to cause idle
+wakeups which resume at the 0x200 address which has to return via
+the idle wakeup code, but the early machine check handler is run
+first.
+
+The case of a no state-loss sleep is broken because the early
+handler uses non-volatile register r1 , which is needed for the wakeup
+protocol, but it is not restored.
+
+Fix this by loading r1 from the MCE exception frame before returning
+to the idle wakeup code. Also update the comment which has become
+stale since the idle rewrite in C.
+
+This crash was found and fix confirmed with a machine check injection
+test in qemu powernv model (which is not upstream in qemu yet).

+Subject: powerpc/crashkernel: Take "mem=" option into account
+
+From: Pingfan Liu <kernelfans@gmail.com>
+
+[ Upstream commit be5470e0c285a68dc3afdea965032f5ddc8269d7 ]
+
+'mem=" option is an easy way to put high pressure on memory during
+some test. Hence after applying the memory limit, instead of total
+mem, the actual usable memory should be considered when reserving mem
+for crashkernel. Otherwise the boot up may experience OOM issue.
+
+E.g. it would reserve 4G prior to the change and 512M afterward, if
+passing
+crashkernel="2G-4G:384M,4G-16G:512M,16G-64G:1G,64G-128G:2G,128G-:4G",
+and mem=5G on a 256G machine.
+
+This issue is powerpc specific because it puts higher priority on
+fadump and kdump reservation than on "mem=". Referring the following
+code:
+ if (fadump_reserve_mem() == 0)
+ reserve_crashkernel();
+ ...
+ /* Ensure that total memory size is page-aligned. */
+ limit = ALIGN(memory_limit ?: memblock_phys_mem_size(), PAGE_SIZE);
+ memblock_enforce_memory_limit(limit);
+
+While on other arches, the effect of "mem=" takes a higher priority
+and pass through memblock_phys_mem_size() before calling
+reserve_crashkernel().

+From: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com>
+
+[ Upstream commit a6e2c226c3d51fd93636320e47cabc8a8f0824c5 ]
+
+With CONFIG_DEBUG_VIRTUAL=y, we can hit a BUG() if we take a hard
+lockup watchdog interrupt when in OPAL mode.
+
+This happens in show_instructions() if the kernel takes the watchdog
+NMI IPI, or any other interrupt, with MSR_IR == 0. show_instructions()
+updates the variable pc in the loop and the second iteration will
+result in BUG().
+
+We hit the BUG_ON due the below check in __va()
+
+ #define __va(x)
+ ({
+ VIRTUAL_BUG_ON((unsigned long)(x) >= PAGE_OFFSET);
+ (void *)(unsigned long)((phys_addr_t)(x) | PAGE_OFFSET);
+ })
+
+Fix it by moving the check out of the loop. Also update nip so that
+the nip == pc check still matches.
+

+Subject: powerpc/perf/hv-24x7: Fix inconsistent output values incase multiple
+ hv-24x7 events run
+
+From: Kajol Jain <kjain@linux.ibm.com>
+
+[ Upstream commit b4ac18eead28611ff470d0f47a35c4e0ac080d9c ]
+
+Commit 2b206ee6b0df ("powerpc/perf/hv-24x7: Display change in counter
+values")' added to print _change_ in the counter value rather then raw
+value for 24x7 counters. Incase of transactions, the event count
+is set to 0 at the beginning of the transaction. It also sets
+the event's prev_count to the raw value at the time of initialization.
+Because of setting event count to 0, we are seeing some weird behaviour,
+whenever we run multiple 24x7 events at a time.
+
+For example:
+
+command#: ./perf stat -e "{hv_24x7/PM_MCS01_128B_RD_DISP_PORT01,chip=0/,
+ hv_24x7/PM_MCS01_128B_RD_DISP_PORT01,chip=1/}"
+ -C 0 -I 1000 sleep 100
+
+ 1.000121704 120 hv_24x7/PM_MCS01_128B_RD_DISP_PORT01,chip=0/
+ 1.000121704 5 hv_24x7/PM_MCS01_128B_RD_DISP_PORT01,chip=1/

+ 2.000357733 10 hv_24x7/PM_MCS01_128B_RD_DISP_PORT01,chip=1/
+ 3.000495215 18,446,744,073,709,551,616 hv_24x7/PM_MCS01_128B_RD_DISP_PORT01,chip=0/

+
+Getting these large values in case we do -I.
+
+As we are setting event_count to 0, for interval case, overall event_count is not
+coming in incremental order. As we may can get new delta lesser then previous count.
+Because of which when we print intervals, we are getting negative value which create
+these large values.
+
+This patch removes part where we set event_count to 0 in function
+'h_24x7_event_read'. There won't be much impact as we do set event->hw.prev_count
+to the raw value at the time of initialization to print change value.
+
+With this patch
+In power9 platform
+
+command#: ./perf stat -e "{hv_24x7/PM_MCS01_128B_RD_DISP_PORT01,chip=0/,

+Subject: powerpc/ps3: Fix kexec shutdown hang
+
+From: Geoff Levand <geoff@infradead.org>
+
+[ Upstream commit 126554465d93b10662742128918a5fc338cda4aa ]
+
+The ps3_mm_region_destroy() and ps3_mm_vas_destroy() routines
+are called very late in the shutdown via kexec's mmu_cleanup_all
+routine. By the time mmu_cleanup_all runs it is too late to use
+udbg_printf, and calling it will cause PS3 systems to hang.
+
+Remove all debugging statements from ps3_mm_region_destroy() and
+ps3_mm_vas_destroy() and replace any error reporting with calls
+to lv1_panic.
+
+With this change builds with 'DEBUG' defined will not cause kexec
+reboots to hang, and builds with 'DEBUG' defined or not will end
+in lv1_panic if an error is encountered.

+
+The problem originates from setting the segment boundary of the
+request queue to -1UL. This makes get_max_segment_size() return zero
+when offset is zero, whatever the max segment size. The test with
+BLK_SEG_BOUNDARY_MASK fails and 'mask - (mask & offset) + 1' overflows
+to zero in the return statement.
+
+Not setting the segment boundary and using the default
+value (BLK_SEG_BOUNDARY_MASK) fixes the problem.

+From: Qiushi Wu <wu000273@umn.edu>
+
+[ Upstream commit 0b8e125e213204508e1b3c4bdfe69713280b7abd ]
+
+kobject_init_and_add() takes reference even when it fails. If this
+function returns an error, kobject_put() must be called to properly clean
+up the memory associated with the object. Previous
+commit b8eb718348b8 ("net-sysfs: Fix reference count leak in
+rx|netdev_queue_add_kobject") fixed a similar problem.

+Subject: remoteproc: Fix IDR initialisation in rproc_alloc()
+
+From: Alex Elder <elder@linaro.org>
+
+[ Upstream commit 6442df49400b466431979e7634849a464a5f1861 ]
+
+If ida_simple_get() returns an error when called in rproc_alloc(),
+put_device() is called to clean things up. By this time the rproc
+device type has been assigned, with rproc_type_release() as the
+release function.
+
+The first thing rproc_type_release() does is call:
+ idr_destroy(&rproc->notifyids);
+
+But at the time the ida_simple_get() call is made, the notifyids
+field in the remoteproc structure has not been initialized.
+
+I'm not actually sure this case causes an observable problem, but
+it's incorrect. Fix this by initializing the notifyids field before
+calling ida_simple_get() in rproc_alloc().

+before rtc_register_device(). But in the error path of
+rtc_register_device(), the mc13xxx_unlock() is called again,

+
+qdio_establish() calls qdio_setup_thinint() via qdio_setup_irq().
+If the subsequent qdio_establish_thinint() fails, we miss to put the
+DSCI again. Thus the DSCI isn't available for re-use. Given enough of

+
+Merge qdio_setup_thinint() into qdio_establish_thinint(), and deal with

+Subject: scsi: core: free sgtables in case command setup fails
+
+From: Johannes Thumshirn <johannes.thumshirn@wdc.com>
+
+[ Upstream commit 20a66f2bf280277ab5bb22e27445153b4eb0ac88 ]
+
+In case scsi_setup_fs_cmnd() fails we're not freeing the sgtables allocated
+by scsi_init_io(), thus we leak the allocated memory.
+
+Free the sgtables allocated by scsi_init_io() in case scsi_setup_fs_cmnd()
+fails.
+
+Technically scsi_setup_scsi_cmnd() does not suffer from this problem as it
+can only fail if scsi_init_io() fails, so it does not have sgtables
+allocated. But to maintain symmetry and as a measure of defensive
+programming, free the sgtables on scsi_setup_scsi_cmnd() failure as well.
+scsi_mq_free_sgtables() has safeguards against double-freeing of memory so
+this is safe to do.
+
+While we're at it, rename scsi_mq_free_sgtables() to scsi_free_sgtables().

+
+[ Upstream commit e16b9ed61e078d836a0f24a82080cf29d7539c7e ]
+
+We found out that after phy up, the hardware reports another oob interrupt
+but did not follow a phy up interrupt:
+
+oob ready -> phy up -> DEV found -> oob read -> wait phy up -> timeout
+
+We run link reset when wait phy up timeout, and it send a normal disk into
+reset processing. So we made some circumvention action in the code, so that
+this abnormal oob interrupt will not start the timer to wait for phy up.

+Subject: scsi: ibmvscsi: Don't send host info in adapter info MAD after LPM
+
+From: Tyrel Datwyler <tyreld@linux.ibm.com>
+
+[ Upstream commit 4919b33b63c8b69d8dcf2b867431d0e3b6dc6d28 ]
+
+The adapter info MAD is used to send the client info and receive the host
+info as a response. A persistent buffer is used and as such the client info
+is overwritten after the response. During the course of a normal adapter
+reset the client info is refreshed in the buffer in preparation for sending
+the adapter info MAD.
+
+However, in the special case of LPM where we reenable the CRQ instead of a
+full CRQ teardown and reset we fail to refresh the client info in the
+adapter info buffer. As a result, after Live Partition Migration (LPM) we
+erroneously report the host's info as our own.

+Subject: scsi: lpfc: Fix lpfc_nodelist leak when processing unsolicited event
+
+From: Xiyu Yang <xiyuyang19@fudan.edu.cn>
+
+[ Upstream commit 7217e6e694da3aae6d17db8a7f7460c8d4817ebf ]
+
+In order to create or activate a new node, lpfc_els_unsol_buffer() invokes
+lpfc_nlp_init() or lpfc_enable_node() or lpfc_nlp_get(), all of them will
+return a reference of the specified lpfc_nodelist object to "ndlp" with
+increased refcnt.
+
+When lpfc_els_unsol_buffer() returns, local variable "ndlp" becomes
+invalid, so the refcount should be decreased to keep refcount balanced.
+
+The reference counting issue happens in one exception handling path of
+lpfc_els_unsol_buffer(). When "ndlp" in DEV_LOSS, the function forgets to
+decrease the refcnt increased by lpfc_nlp_init() or lpfc_enable_node() or
+lpfc_nlp_get(), causing a refcnt leak.
+
+Fix this issue by calling lpfc_nlp_put() when "ndlp" in DEV_LOSS.

+Subject: scsi: qedf: Fix crash when MFW calls for protocol stats while
+ function is still probing
+
+From: Chad Dupuis <cdupuis@marvell.com>
+
+[ Upstream commit ad40f5256095c68dc17c991eb976261d5ea2daaa ]
+
+The MFW may make a call to qed and then to qedf for protocol statistics
+while the function is still probing. If this happens it's possible that
+some members of the struct qedf_ctx may not be fully initialized which can
+result in a NULL pointer dereference or general protection fault.
+
+To prevent this, add a new flag call QEDF_PROBING and set it when the
+__qedf_probe() function is active. Then in the qedf_get_protocol_tlv_data()
+function we can check if the function is still probing and return
+immediantely before any uninitialized structures can be touched.

+Subject: scsi: qedi: Check for buffer overflow in qedi_set_path()
+
+From: Dan Carpenter <dan.carpenter@oracle.com>
+
+[ Upstream commit 4a4c0cfb4be74e216dd4446b254594707455bfc6 ]
+
+Smatch complains that the "path_data->handle" variable is user controlled.
+It comes from iscsi_set_path() so that seems possible. It's harmless to
+add a limit check.
+
+The qedi->ep_tbl[] array has qedi->max_active_conns elements (which is
+always ISCSI_MAX_SESS_PER_HBA (4096) elements). The array is allocated in
+the qedi_cm_alloc_mem() function.
+
+Link: https://lore.kernel.org/r/20200428131939.GA696531@mwanda
+Fixes: ace7f46ba5fd ("scsi: qedi: Add QLogic FastLinQ offload iSCSI driver framework.")

+Subject: scsi: qedi: Do not flush offload work if ARP not resolved

+From: Nilesh Javali <njavali@marvell.com>
+
+[ Upstream commit 927527aea0e2a9c1d336c7d33f77f1911481d008 ]
+
+For an unreachable target, offload_work is not initialized and the endpoint
+state is set to OFLDCONN_NONE. This results in a WARN_ON due to the check
+of the work function field being set to zero.

+The issue happens because no real ISP reset is executed. The
+qla2x00_abort_isp(scsi_qla_host_t *vha) function expects that
+vha->flags.online will be not zero for ISP reset procedure. This patch
+sets vha->flags.online to 1 before calling ->abort_isp() for starting the
+ISP reset.

+Subject: scsi: target: loopback: Fix READ with data and sensebytes
+
+From: Bodo Stroesser <bstroesser@ts.fujitsu.com>
+
+[ Upstream commit c68a56736c129f5dd1632856956f9c3e04bae200 ]
+
+We use tcm_loop with tape emulations running on tcmu.
+
+In case application reads a short tape block with a longer READ, or a long
+tape block with a short READ, according to SCC spec data has to be
+tranferred _and_ sensebytes with ILI set and information field containing
+the residual count. Similar problem also exists when using fixed block
+size in READ.
+
+Up to now tcm_loop is not prepared to handle sensebytes if input data is
+provided, as in tcm_loop_queue_data_in() it only sets SAM_STAT_GOOD and, if
+necessary, the residual count.
+
+To fix the bug, the same handling for sensebytes as present in
+tcm_loop_queue_status() must be done in tcm_loop_queue_data_in() also.
+
+After adding this handling, the two function now are nearly identical, so I
+created a single function with two wrappers.

+
+From: Bodo Stroesser <bstroesser@ts.fujitsu.com>
+
+[ Upstream commit 61fb2482216679b9e1e797440c148bb143a5040a ]
+
+When tcmu queues a new command - no matter whether in command ring or in
+qfull_queue - a cmd_id from IDR udev->commands is assigned to the command.
+
+If userspace sends a wrong command completion containing the cmd_id of a
+command on the qfull_queue, tcmu_handle_completions() finds the command in
+the IDR and calls tcmu_handle_completion() for it. This might do some nasty
+things because commands in qfull_queue do not have a valid dbi list.
+
+To fix this bug, we no longer add queued commands to the idr. Instead the
+cmd_id is assign when a command is written to the command ring.
+
+Due to this change I had to adapt the source code at several places where
+up to now an idr_for_each had been done.

+
+From: Can Guo <cang@codeaurora.org>
+
+[ Upstream commit be32acff43800c87dc5c707f5d47cc607b76b653 ]
+
+Urgent bkops level is used to compare against actual bkops status read from
+UFS device. Urgent bkops level is set during initialization and might be
+updated in exception event handler during runtime. But it should not be
+updated to the actual bkops status every time when auto bkops is toggled.
+Otherwise, if urgent bkops level is updated to 0, auto bkops shall always
+be kept enabled.

+Subject: scsi: ufs-qcom: Fix scheduling while atomic issue
+
+From: Jeffrey Hugo <jeffrey.l.hugo@gmail.com>
+
+[ Upstream commit 3be60b564de49875e47974c37fabced893cd0931 ]
+
+ufs_qcom_dump_dbg_regs() uses usleep_range, a sleeping function, but can be
+called from atomic context in the following flow:
+
+ufshcd_intr -> ufshcd_sl_intr -> ufshcd_check_errors ->
+ufshcd_print_host_regs -> ufshcd_vops_dbg_register_dump ->
+ufs_qcom_dump_dbg_regs
+
+This causes a boot crash on the Lenovo Miix 630 when the interrupt is
+handled on the idle thread.
+
+Fix the issue by switching to udelay().

+Subject: scsi: vhost: Notify TCM about the maximum sg entries supported per
+ command
+
+From: Sudhakar Panneerselvam <sudhakar.panneerselvam@oracle.com>
+
+[ Upstream commit 5ae6a6a915033bfee79e76e0c374d4f927909edc ]
+
+vhost-scsi pre-allocates the maximum sg entries per command and if a
+command requires more than VHOST_SCSI_PREALLOC_SGLS entries, then that
+command is failed by it. This patch lets vhost communicate the max sg limit
+when it registers vhost_scsi_ops with TCM. With this change, TCM would
+report the max sg entries through "Block Limits" VPD page which will be
+typically queried by the SCSI initiator during device discovery. By knowing
+this limit, the initiator could ensure the maximum transfer length is less
+than or equal to what is reported by vhost-scsi.

+with baud rates up to 1/16 of a reference frequency. It's expected from
+most of the currently supported UART controllers. That's why the former
+version of serial8250_get_baud_rate() method called uart_get_baud_rate()
+with min and max baud rates passed as (port->uartclk / 16 / UART_DIV_MAX)
+and ((port->uartclk + tolerance) / 16) respectively. Doing otherwise, like
+it was suggested in commit ("serial: 8250_mtk: support big baud rate."),
+caused acceptance of bauds, which was higher than the normal UART
+controllers actually supported. As a result if some user-space program
+requested to set a baud greater than (uartclk / 16) it would have been
+permitted without truncation, but then serial8250_get_divisor(baud)
+(which calls uart_get_divisor() to get the reference clock divisor) would
+have returned a zero divisor. Setting zero divisor will cause an
+unpredictable effect varying from chip to chip. In case of DW APB UART the
+communications just stop.
+
+Lets fix this problem by getting back the limitation of (uartclk +
+tolerance) / 16 maximum baud supported by the generic 8250 port. Mediatek
+8250 UART ports driver developer shouldn't have touched it in the first
+place notably seeing he already provided a custom version of set_termios()
+callback in that glue-driver which took into account the extended baud
+rate values and accordingly updated the standard and vendor-specific
+divisor latch registers anyway.

+
+Which seems to be due to the fact that after allocating the uap
+structure, nothing initializes the spinlock.
+
+Its a little confusing, as uart_port_spin_lock_init() is one
+place where the lock is supposed to be initialized, but it has
+an exception for the case where the port is a console.
+
+This makes it seem like a deeper fix is needed to properly
+register the console, but I'm not sure what that entails, and
+Andy suggested that this approach is less invasive.
+
+Thus, this patch resolves the issue by initializing the spinlock
+in the driver, and resolves the resulting warning.

+Subject: SoC: rsnd: add interrupt support for SSI BUSIF buffer
+
+From: Yongbo Zhang <giraffesnn123@gmail.com>
+
+[ Upstream commit 66c705d07d784fb6b4622c6e47b6acae357472db ]
+
+SSI BUSIF buffer is possible to overflow or underflow, especially in a
+hypervisor environment. If there is no interrupt support, it will eventually
+lead to errors in pcm data.
+This patch adds overflow and underflow interrupt support for SSI BUSIF buffer.

+[ Upstream commit 454b0289c6b5f2c66164654b80212d15fbef7a03 ]
+
+The pages backing page-table allocations for SRMMU are allocated via

+Subject: staging: gasket: Fix mapping refcnt leak when put attribute fails
+
+From: Xiyu Yang <xiyuyang19@fudan.edu.cn>
+
+[ Upstream commit 57a66838e1494cd881b7f4e110ec685736e8e3ca ]
+
+gasket_sysfs_put_attr() invokes get_mapping(), which returns a reference
+of the specified gasket_sysfs_mapping object to "mapping" with increased
+refcnt.
+
+When gasket_sysfs_put_attr() returns, local variable "mapping" becomes
+invalid, so the refcount should be decreased to keep refcount balanced.
+
+The reference counting issue happens in one path of
+gasket_sysfs_put_attr(). When mapping attribute is unknown, the function
+forgets to decrease the refcnt increased by get_mapping(), causing a
+refcnt leak.
+
+Fix this issue by calling put_mapping() when put attribute fails due to
+unknown attribute.

+Subject: tty: hvc: Fix data abort due to race in hvc_open
+
+From: Raghavendra Rao Ananta <rananta@codeaurora.org>
+
+[ Upstream commit e2bd1dcbe1aa34ff5570b3427c530e4332ecf0fe ]
+
+Potentially, hvc_open() can be called in parallel when two tasks calls
+open() on /dev/hvcX. In such a scenario, if the hp->ops->notifier_add()
+callback in the function fails, where it sets the tty->driver_data to
+NULL, the parallel hvc_open() can see this NULL and cause a memory abort.
+Hence, serialize hvc_open and check if tty->private_data is NULL before
+proceeding ahead.
+
+The issue can be easily reproduced by launching two tasks simultaneously
+that does nothing but open() and close() on /dev/hvcX.
+For example:
+$ ./simple_open_close /dev/hvc0 & ./simple_open_close /dev/hvc0 &

+
+From: Gregory CLEMENT <gregory.clement@bootlin.com>
+
+[ Upstream commit 4dd31f1ffec6c370c3c2e0c605628bf5e16d5c46 ]
+
+When submitting the previous fix "tty: n_gsm: Fix waking up upper tty
+layer when room available". It was suggested to switch from a while to
+a for loop, but when doing it, there was a remaining bogus i++.
+
+This patch removes this i++ and also reorganizes the code making it more
+compact.

+From: Gregory CLEMENT <gregory.clement@bootlin.com>
+
+[ Upstream commit 84d6f81c1fb58b56eba81ff0a36cf31946064b40 ]
+
+For at least some modems like the TELIT LE910, skipping SOF makes
+transfers blocking indefinitely after a short amount of data
+transferred.
+
+Given the small improvement provided by skipping the SOF (just one
+byte on about 100 bytes), it seems better to completely remove this
+"feature" than make it optional.

+
+When the remote wakeup interrupt is triggered, lx_state is resumed from L2
+to L0 state. But when the gadget resume is called, lx_state is still L2.
+This prevents the resume callback to queue any request. Any attempt
+to queue a request from resume callback will result in:

+- dwc2_hsotg_ep_queue() returns -EAGAIN
+
+Call the gadget resume routine after the core is in L0 state.

+Subject: usb: gadget: core: sync interrupt before unbind the udc
+
+From: Peter Chen <peter.chen@nxp.com>
+
+[ Upstream commit 3c73bc52195def14165c3a7d91bdbb33b51725f5 ]
+
+The threaded interrupt handler may still be called after the
+usb_gadget_disconnect is called, it causes the structures used
+at interrupt handler was freed before it uses, eg the
+usb_request. This issue usually occurs we remove the udc function
+during the transfer. Below is the example when doing stress
+test for android switch function, the EP0's request is freed
+by .unbind (configfs_composite_unbind -> composite_dev_cleanup),
+but the threaded handler accesses this request during handling
+setup packet request.
+
+In fact, there is no protection between unbind the udc
+and udc interrupt handling, so we have to avoid the interrupt
+handler is occurred or scheduled during the .unbind flow.

+Subject: usb: gadget: Fix issue with config_ep_by_speed function
+
+From: Pawel Laszczak <pawell@cadence.com>
+
+[ Upstream commit 5d363120aa548ba52d58907a295eee25f8207ed2 ]
+
+This patch adds new config_ep_by_speed_and_alt function which
+extends the config_ep_by_speed about alt parameter.
+This additional parameter allows to find proper usb_ss_ep_comp_descriptor.
+
+Problem has appeared during testing f_tcm (BOT/UAS) driver function.
+
+f_tcm function for SS use array of headers for both BOT/UAS alternate
+setting:
+
+static struct usb_descriptor_header *uasp_ss_function_desc[] = {
+ (struct usb_descriptor_header *) &bot_intf_desc,
+ (struct usb_descriptor_header *) &uasp_ss_bi_desc,
+ (struct usb_descriptor_header *) &bot_bi_ep_comp_desc,
+ (struct usb_descriptor_header *) &uasp_ss_bo_desc,
+ (struct usb_descriptor_header *) &bot_bo_ep_comp_desc,
+
+ (struct usb_descriptor_header *) &uasp_intf_desc,
+ (struct usb_descriptor_header *) &uasp_ss_bi_desc,
+ (struct usb_descriptor_header *) &uasp_bi_ep_comp_desc,
+ (struct usb_descriptor_header *) &uasp_bi_pipe_desc,
+ (struct usb_descriptor_header *) &uasp_ss_bo_desc,
+ (struct usb_descriptor_header *) &uasp_bo_ep_comp_desc,
+ (struct usb_descriptor_header *) &uasp_bo_pipe_desc,
+ (struct usb_descriptor_header *) &uasp_ss_status_desc,
+ (struct usb_descriptor_header *) &uasp_status_in_ep_comp_desc,
+ (struct usb_descriptor_header *) &uasp_status_pipe_desc,
+ (struct usb_descriptor_header *) &uasp_ss_cmd_desc,
+ (struct usb_descriptor_header *) &uasp_cmd_comp_desc,
+ (struct usb_descriptor_header *) &uasp_cmd_pipe_desc,
+ NULL,
+};
+
+The first 5 descriptors are associated with BOT alternate setting,
+and others are associated with UAS.
+
+During handling UAS alternate setting f_tcm driver invokes
+config_ep_by_speed and this function sets incorrect companion endpoint
+descriptor in usb_ep object.
+
+Instead setting ep->comp_desc to uasp_bi_ep_comp_desc function in this
+case set ep->comp_desc to uasp_ss_bi_desc.
+
+This is due to the fact that it searches endpoint based on endpoint
+address:
+
+ for_each_ep_desc(speed_desc, d_spd) {
+ chosen_desc = (struct usb_endpoint_descriptor *)*d_spd;
+ if (chosen_desc->bEndpoitAddress == _ep->address)
+ goto ep_found;
+ }
+
+And in result it uses the descriptor from BOT alternate setting
+instead UAS.
+
+Finally, it causes that controller driver during enabling endpoints
+detect that just enabled endpoint for bot.

+
+[ Upstream commit eafa80041645cd7604c4357b1a0cd4a3c81f2227 ]
+
+Currently pointer ep is being dereferenced before it is null checked
+leading to a null pointer dereference issue. Fix this by only assigning
+pointer udc once ep is known to be not null. Also remove a debug
+message that requires a valid udc which may not be possible at that

+
+From: Nathan Chancellor <natechancellor@gmail.com>
+
+[ Upstream commit 7a0fbcf7c308920bc6116b3a5fb21c8cc5fec128 ]
+
+Clang warns:
+
+drivers/usb/gadget/udc/s3c2410_udc.c:255:11: warning: comparison of
+address of 'ep->queue' equal to a null pointer is always false
+[-Wtautological-pointer-compare]
+ if (&ep->queue == NULL)
+ ~~~~^~~~~ ~~~~
+1 warning generated.
+
+It is not wrong, queue is not a pointer so if ep is not NULL, the
+address of queue cannot be NULL. No other driver does a check like this
+and this check has been around since the driver was first introduced,
+presumably with no issues so it does not seem like this check should be
+something else. Just remove it.
+
+Commit afe956c577b2d ("kbuild: Enable -Wtautological-compare") exposed
+this but it is not the root cause of the warning.

+The function ehci_mxc_drv_probe() does not perform sufficient error
+checking after executing platform_get_irq(), thus fix it.

+Subject: usb: host: ehci-platform: add a quirk to avoid stuck
+
+From: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com>
+
+[ Upstream commit cc7eac1e4afdd151085be4d0341a155760388653 ]
+
+Since EHCI/OHCI controllers on R-Car Gen3 SoCs are possible to
+be getting stuck very rarely after a full/low usb device was
+disconnected. To detect/recover from such a situation, the controllers
+require a special way which poll the EHCI PORTSC register and changes
+the OHCI functional state.
+
+So, this patch adds a polling timer into the ehci-platform driver,
+and if the ehci driver detects the issue by the EHCI PORTSC register,
+the ehci driver removes a companion device (= the OHCI controller)
+to change the OHCI functional state to USB Reset once. And then,
+the ehci driver adds the companion device again.

+
+[ Upstream commit aa8ba13cae3134b8ef1c1b6879f66372531da738 ]
+
+kobject_init_and_add() takes reference even when it fails.
+If this function returns an error, kobject_put() must be called to
+properly clean up the memory associated with the object. Thus,
+replace kfree() by kobject_put() to fix this issue. Previous
+commit "b8eb718348b8" fixed a similar problem.

+Subject: vfio-pci: Mask cap zero
+
+From: Alex Williamson <alex.williamson@redhat.com>
+
+[ Upstream commit bc138db1b96264b9c1779cf18d5a3b186aa90066 ]
+
+The PCI Code and ID Assignment Specification changed capability ID 0
+from reserved to a NULL capability in the v1.1 revision. The NULL
+capability is defined to include only the 16-bit capability header,
+ie. only the ID and next pointer. Unfortunately vfio-pci creates a
+map of config space, where ID 0 is used to reserve the standard type
+0 header. Finding an actual capability with this ID therefore results
+in a bogus range marked in that map and conflicts with subsequent
+capabilities. As this seems to be a dummy capability anyway and we
+already support dropping capabilities, let's hide this one rather than
+delving into the potentially subtle dependencies within our map.
+
+Seen on an NVIDIA Tesla T4.

+Subject: virtiofs: schedule blocking async replies in separate worker
+
+From: Vivek Goyal <vgoyal@redhat.com>
+
+[ Upstream commit bb737bbe48bea9854455cb61ea1dc06e92ce586c ]
+
+In virtiofs (unlike in regular fuse) processing of async replies is
+serialized. This can result in a deadlock in rare corner cases when
+there's a circular dependency between the completion of two or more async
+replies.
+
+Such a deadlock can be reproduced with xfstests:generic/503 if TEST_DIR ==
+SCRATCH_MNT (which is a misconfiguration):
+
+ - Process A is waiting for page lock in worker thread context and blocked
+ (virtio_fs_requests_done_work()).
+ - Process B is holding page lock and waiting for pending writes to
+ finish (fuse_wait_on_page_writeback()).
+ - Write requests are waiting in virtqueue and can't complete because
+ worker thread is blocked on page lock (process A).
+
+Fix this by creating a unique work_struct for each async reply that can
+block (O_DIRECT read).

+Subject: watchdog: da9062: No need to ping manually before setting timeout
+
+From: Stefan Riedmueller <s.riedmueller@phytec.de>
+
+[ Upstream commit a0948ddba65f4f6d3cfb5e2b84685485d0452966 ]
+
+There is actually no need to ping the watchdog before disabling it
+during timeout change. Disabling the watchdog already takes care of
+resetting the counter.
+
+This fixes an issue during boot when the userspace watchdog handler takes
+over and the watchdog is already running. Opening the watchdog in this case
+leads to the first ping and directly after that without the required
+heartbeat delay a second ping issued by the set_timeout call. Due to the
+missing delay this resulted in a reset.

+ c84cb3735fd5 ("x86/apic: Move TSC deadline timer debug printk")
+
+removed the message which said that the deadline timer was enabled.
+It added a pr_debug() message which is issued when deadline timer
+validation succeeds.
+
+Well, issued only when CONFIG_DYNAMIC_DEBUG is enabled - otherwise
+pr_debug() calls get optimized away if DEBUG is not defined in the
+compilation unit.
+
+Therefore, make the above message pr_info() so that it is visible in
+dmesg.

+Subject: x86/idt: Keep spurious entries unset in system_vectors
+
+From: Vitaly Kuznetsov <vkuznets@redhat.com>
+
+[ Upstream commit 1f1fbc70c10e81f70e9fbe2102d439c883269811 ]
+
+With commit dc20b2d52653 ("x86/idt: Move interrupt gate initialization to
+IDT code") non assigned system vectors are also marked as used in
+'used_vectors' (now 'system_vectors') bitmap. This makes checks in
+arch_show_interrupts() whether a particular system vector is allocated to
+always pass and e.g. 'Hyper-V reenlightenment interrupts' entry always
+shows up in /proc/interrupts.
+
+Another side effect of having all unassigned system vectors marked as used
+is that irq_matrix_debug_show() will wrongly count them among 'System'
+vectors.
+
+As it is now ensured that alloc_intr_gate() is not called after init, it is
+possible to leave unused entries in 'system_vectors' unset to fix these
+issues.

+Subject: x86/purgatory: Disable various profiling and sanitizing options
+
+From: Hans de Goede <hdegoede@redhat.com>
+
+[ Upstream commit e2ac07c06058ae2d58b45bbf2a2a352771d76fcb ]
+
+Since the purgatory is a special stand-alone binary, various profiling
+and sanitizing options must be disabled. Having these options enabled
+typically will cause dependencies on various special symbols exported by
+special libs / stubs used by these frameworks. Since the purgatory is
+special, it is not linked against these stubs causing missing symbols in
+the purgatory if these options are not disabled.
+
+Sync the set of disabled profiling and sanitizing options with that from
+drivers/firmware/efi/libstub/Makefile, adding
+-DDISABLE_BRANCH_PROFILING to the CFLAGS and setting:
+
+ GCOV_PROFILE := n
+ UBSAN_SANITIZE := n
+
+This fixes broken references to ftrace_likely_update() when
+CONFIG_TRACE_BRANCH_PROFILING is enabled and to __gcov_init() and
+__gcov_exit() when CONFIG_GCOV_KERNEL is enabled.
