+
+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: 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);
+ ...

+ }
+
+ memset(&sa, 0, sizeof(sa));
+ sa.salg_family = AF_ALG;
+ strcpy((char *) sa.salg_type, "rng");
+ strcpy((char *) sa.salg_name, "stdrng");
+
+ if (bind(sockfd, (struct sockaddr *) &sa, sizeof(sa)) < 0) {
+ perror("bind");
+ return 1;
+ }
+
+ /* Accept a "connection" and close it; repeat. */
+ while (!close(accept(sockfd, NULL, 0)));
+
+ return 0;
+ }
+
+ $ gcc -o aa-refcnt-af_alg aa-refcnt-af_alg.c
+
+ $ ./aa-refcnt-af_alg

+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: 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'.

+
+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 199a5e8fda54ab3c8c6f6bf980c004e97ebf5ccb ]
+
+The Toshiba Encore WT10-A tablet almost fully works with the default
+settings for Bay Trail CR devices. The only issue is that it uses a
+digital mic. connected the the DMIC1 input instead of an analog mic.
+
+Add a quirk for this model using the default settings with the input-map
+replaced with BYT_RT5640_DMIC1_MAP.

+[ Upstream commit 79d4f823a06796656289f97b922493da5690e46c ]
+
+The Asus T101HA uses the default jack-detect mode 3, but instead of

+like the Asus T100HA. Note unlike the T100HA its jack-detect is not

+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
+ bdput (the last one)
+ bdev_evict_inode
+
+ access bdev => use after free

+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: 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")

+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: 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.

+
+[ Upstream commit 489dc0f06a5837f87482c0ce61d830d24e17082e ]

+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.

+Subject: elfnote: mark all .note sections SHF_ALLOC
+
+From: Nick Desaulniers <ndesaulniers@google.com>
+
+[ Upstream commit 51da9dfb7f20911ae4e79e9b412a9c2d4c373d4b ]
+
+ELFNOTE_START allows callers to specify flags for .pushsection assembler
+directives. All callsites but ELF_NOTE use "a" for SHF_ALLOC. For vdso's
+that explicitly use ELF_NOTE_START and BUILD_SALT, the same section is
+specified twice after preprocessing, once with "a" flag, once without.
+Example:
+
+.pushsection .note.Linux, "a", @note ;
+.pushsection .note.Linux, "", @note ;
+
+While GNU as allows this ordering, it warns for the opposite ordering,
+making these directives position dependent. We'd prefer not to precisely
+match this behavior in Clang's integrated assembler. Instead, the non
+__ASSEMBLY__ definition of ELF_NOTE uses
+__attribute__((section(".note.Linux"))) which is created with SHF_ALLOC,
+so let's make the __ASSEMBLY__ definition of ELF_NOTE consistent with C
+and just always use "a" flag.
+
+This allows Clang to assemble a working mainline (5.6) kernel via:
+$ make CC=clang AS=clang

+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.

+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.

+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: 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.

+
+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]

+Subject: Input: mms114 - add extra compatible for mms345l
+
+From: Stephan Gerhold <stephan@gerhold.net>
+
+[ Upstream commit 7842087b0196d674ed877d768de8f2a34d7fdc53 ]
+
+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.

+
+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.

+Subject: mksysmap: Fix the mismatch of '.L' symbols in System.map
+
+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/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.

+
+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.

+From: Xiyu Yang <xiyuyang19@fudan.edu.cn>
+
+[ 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.

+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.

+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.

+
+[ 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.

+
+[ 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.

+ 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/ASPM: Allow ASPM on links to PCIe-to-PCI/PCI-X Bridges
+
+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.

+Subject: PCI: dwc: Fix inner MSI IRQ domain registration
+
+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".

+
+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.

+
+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.

+
+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),

+
+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

+ ...
+ 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/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().

+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 8 hv_24x7/PM_MCS01_128B_RD_DISP_PORT01,chip=0/
+ 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/
+ 3.000495215 18,446,744,073,709,551,616 hv_24x7/PM_MCS01_128B_RD_DISP_PORT01,chip=1/
+ 4.000641884 56 hv_24x7/PM_MCS01_128B_RD_DISP_PORT01,chip=0/

+ 5.000791887 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/,
+ hv_24x7/PM_MCS01_128B_RD_DISP_PORT01,chip=1/}"

+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.

+
+From: Nicholas Piggin <npiggin@gmail.com>
+
+[ Upstream commit deb70f7a35a22dffa55b2c3aac71bc6fb0f486ce ]
+
+This was discovered developing qemu fwnmi sreset support. This
+off-by-one bug means the last 16 bytes of the rtas area can not
+be used for a 16 byte save area.
+
+It's not a serious bug, and QEMU implementation has to retain a
+workaround for old kernels, but it's good to tighten it.

+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.

+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().

+From: Julian Wiedmann <jwi@linux.ibm.com>
+
+[ Upstream commit 75e82bec6b2622c6f455b7a543fb5476a5d0eed7 ]
+
+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
+such errors, we could end up with having only the shared DSCI available.
+
+Merge qdio_setup_thinint() into qdio_establish_thinint(), and deal with
+such an error internally.

+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.")

+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: tcmu: Userspace must not complete queued commands
+
+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: serial: 8250: Fix max baud limit in generic 8250 port
+
+From: Serge Semin <Sergey.Semin@baikalelectronics.ru>
+
+[ Upstream commit 7b668c064ec33f3d687c3a413d05e355172e6c92 ]
+
+Standard 8250 UART ports are designed in a way so they can communicate
+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.

+
+Get drvdata directly from parent instead of ngd dev, as ngd
+dev can probe defer and previously set drvdata will become null.

+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.

+On error the function ti_bandgap_get_sensor_data() returns the error
+code in ERR_PTR() but we only checked if the return value is NULL or

+
+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 &

+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

+From: Fabrice Gasnier <fabrice.gasnier@st.com>
+
+[ Upstream commit 8c935deacebb8fac8f41378701eb79d12f3c2e2d ]
+
+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:
+- "submit request only in active state" debug message to be issued
+- dwc2_hsotg_ep_queue() returns -EAGAIN
+

+
+[ Upstream commit 8d99087c2db863c5fa3a4a1f3cb82b3a493705ca ]
+
+If dwc3 fails to issue START_TRANSFER/UPDATE_TRANSFER command, then we
+should properly end an active transfer and give back all the started
+requests. However if it's for an isoc endpoint, the failure maybe due to
+bus-expiry status. In this case, don't give back the requests and wait
+for the next retry.

+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.

+
+Clang warns:

+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

+Subject: USB: host: ehci-mxc: Add error handling in ehci_mxc_drv_probe()
+
+From: Tang Bin <tangbin@cmss.chinamobile.com>
+
+[ Upstream commit d49292025f79693d3348f8e2029a8b4703be0f0a ]
+
+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.

+
+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: 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.

+
+From: Borislav Petkov <bp@suse.de>
+
+[ Upstream commit de308d1815c9e8fe602a958c5c76142ff6501d75 ]
+
+The commit
+
+ 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.

+Subject: yam: fix possible memory leak in yam_init_driver
+
+From: Wang Hai <wanghai38@huawei.com>
+
+[ Upstream commit 98749b7188affbf2900c2aab704a8853901d1139 ]
+
+If register_netdev(dev) fails, free_netdev(dev) needs
+to be called, otherwise a memory leak will occur.
+
+Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
