+Subject: ALSA: hda/realtek - Add mute LED quirk for HP Spectre x360
+
+From: Alexandru Gagniuc <mr.nuke.me@gmail.com>
+
+[ Upstream commit 56e40eb6d656194e55ce2012fee9d5a496270aaa ]
+
+This device has the same issues as the HP x360 wrt the MUTE LED and
+the front speakers not working. This patch fixes the MUTE LED issue,
+but doesn't touch the HDA verbs. The fix for the x360 does not work
+on the Spectre.

+
+commit c83532fb0fe053d2e43e9387354cb1b52ba26427 upstream.
+
+SWAP support on ARC was fixed earlier by
+commit 6e3761145a9b ("ARC: Fix CONFIG_SWAP")
+so now we may safely enable it on platforms that
+have external media like USB and SD-card.
+

+Subject: ata: libahci: Allow reconfigure of DEVSLP register
+
+From: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>
+
+[ Upstream commit 11c291461b6ea8d1195a96d6bba6673a94aacebc ]
+
+There are two modes in which DEVSLP can be entered. The OS initiated or
+hardware autonomous.
+
+In hardware autonomous mode, BIOS configures the AHCI controller and the
+device to enable DEVSLP. But they may not be ideal for all cases. So in
+this case, OS should be able to reconfigure DEVSLP register.
+
+Currently if the DEVSLP is already enabled, we can't set again as it will
+simply return. There are some systems where the firmware is setting high
+DITO by default, in this case we can't modify here to correct settings.
+With the default in several seconds, we are not able to transition to
+DEVSLP.
+
+This change will allow reconfiguration of devslp register if DITO is
+different.

+We have seen that on some platforms, SATA device never show any DEVSLP

+
+[ Upstream commit 673bc519c55843c68c3aecff71a4101e79d28d2b ]
+
+The tx completion of multiple mgmt frames can be bundled
+in a single event and sent by the firmware to host, if this
+capability is not disabled explicitly by the host. If the host
+cannot handle the bundled mgmt tx completion, this capability
+support needs to be disabled in the wmi init cmd, sent to the firmware.
+
+Add the host capability indication flag in the wmi ready command,
+to let firmware know the features supported by the host driver.
+This field is ignored if it is not supported by firmware.
+
+Set the host capability indication flag(i.e. host_capab) to zero,
+for disabling the support of bundle mgmt tx completion. This will
+indicate the firmware to send completion event for every mgmt tx
+completion, instead of bundling them together and sending in a single
+event.

+
+From: Sven Eckelmann <sven.eckelmann@openmesh.com>
+
+[ Upstream commit 3f259111583801013cb605bb4414aa529adccf1c ]
+
+The QCA4019 hw1.0 firmware 10.4-3.2.1-00050 and 10.4-3.5.3-00053 (and most
+likely all other) seem to ignore the WMI_CHAN_FLAG_DFS flag during the
+scan. This results in transmission (probe requests) on channels which are
+not "available" for transmissions.
+
+Since the firmware is closed source and nothing can be done from our side
+to fix the problem in it, the driver has to work around this problem. The
+WMI_CHAN_FLAG_PASSIVE seems to be interpreted by the firmware to not
+scan actively on a channel unless an AP was detected on it. Simple probe
+requests will then be transmitted by the STA on the channel.
+
+ath10k must therefore also use this flag when it queues a radar channel for
+scanning. This should reduce the chance of an active scan when the channel
+might be "unusable" for transmissions.

+
+From: Ming Lei <ming.lei@redhat.com>
+
+[ Upstream commit 75d6e175fc511e95ae3eb8f708680133bc211ed3 ]
+
+The passed 'nr' from userspace represents the total depth, meantime
+inside 'struct blk_mq_tags', 'nr_tags' stores the total tag depth,
+and 'nr_reserved_tags' stores the reserved part.
+
+There are two issues in blk_mq_tag_update_depth() now:
+
+1) for growing tags, we should have used the passed 'nr', and keep the
+number of reserved tags not changed.
+
+2) the passed 'nr' should have been used for checking against
+'tags->nr_tags', instead of number of the normal part.
+
+This patch fixes the above two cases, and avoids kernel crash caused
+by wrong resizing sbitmap queue.

+
+From: Stefan Hajnoczi <stefanha@redhat.com>
+
+[ Upstream commit b7751410c180a05fdc21268f8661b1480169b0df ]
+
+dax_pmem_percpu_exit() waits for dax_pmem_percpu_release() to invoke the
+dax_pmem->cmp completion. Unfortunately this approach to cleaning up
+the percpu_ref only works after devm_memremap_pages() was successful.
+
+If devm_add_action_or_reset() or devm_memremap_pages() fails,
+dax_pmem_percpu_release() is not invoked. Therefore
+dax_pmem_percpu_exit() hangs waiting for the completion:
+
+ rc = devm_add_action_or_reset(dev, dax_pmem_percpu_exit,
+ &dax_pmem->ref);
+ if (rc)
+ return rc;
+
+ dax_pmem->pgmap.ref = &dax_pmem->ref;
+ addr = devm_memremap_pages(dev, &dax_pmem->pgmap);
+
+Avoid the hang by calling percpu_ref_exit() in the error paths instead
+of going through dax_pmem_percpu_exit().

+From: Anthony Koo <Anthony.Koo@amd.com>
+
+[ Upstream commit 9907704174e0ad4ed02766fac4049971e583323d ]
+
+[Why]
+PSR_SET command is sent to the microcontroller in order to initialize
+parameters needed for PSR feature, such as telling the microcontroller
+which pipe is driving the PSR supported panel. When this command is
+skipped or fails, the microcontroller may program the wrong thing if
+driver tries to enable PSR.
+
+[How]
+If PSR_SET fails, do not set psr_enable flag to indicate the feature is
+not yet initialized.

+From: Yunlong Song <yunlong.song@huawei.com>
+
+[ Upstream commit 3611ce9911267cb93d364bd71ddea6821278d11f ]
+
+For the case when sbi->segs_per_sec > 1, take section:segment = 5 for
+example, if segment 1 is just used and allocate new segment 2, and the
+blocks of segment 1 is invalidated, at this time, the previous code will
+use __set_test_and_free to free the free_secmap and free_sections++,
+this is not correct since it is still a current section, so fix it.

+Subject: f2fs: fix to detect looped node chain correctly
+
+From: Chao Yu <yuchao0@huawei.com>
+
+[ Upstream commit 82902c06bd17dbf6e8184299842ca5c68880970f ]
+
+Below dmesg was printed when testing generic/388 of fstest:
+
+F2FS-fs (zram1): find_fsync_dnodes: detect looped node chain, blkaddr:526615, next:526616
+F2FS-fs (zram1): Cannot recover all fsync data errno=-22

+F2FS-fs (zram1): Cannot recover all fsync data errno=-22
+
+The reason is that we initialize free_blocks with free blocks of
+filesystem, so if filesystem is full, free_blocks can be zero,
+below condition will be true, so that, it will fail recovery.
+
+if (++loop_cnt >= free_blocks ||
+ blkaddr == next_blkaddr_of_node(page))
+
+To fix this issue, initialize free_blocks with correct value which
+includes over-privision blocks.

+
+From: Chao Yu <yuchao0@huawei.com>
+
+[ Upstream commit 76d56d4ab4f2a9e4f085c7d77172194ddaccf7d2 ]
+
+If FI_EXTRA_ATTR is set in inode by fuzzing, inode.i_addr[0] will be
+parsed as inode.i_extra_isize, then in __recover_inline_status, inline
+data address will beyond boundary of page, result in accessing invalid
+memory.
+
+So in this condition, during reading inode page, let's do sanity check
+with EXTRA_ATTR feature of fs and extra_attr bit of inode, if they're
+inconsistent, deny to load this inode.

+The kernel still mounts the image. If you run the following program on the mounted folder mnt,
+
+(poc.c)
+
+static void activity(char *mpoint) {
+
+ char *foo_bar_baz;
+ int err;
+
+ static int buf[8192];
+ memset(buf, 0, sizeof(buf));
+
+ err = asprintf(&foo_bar_baz, "%s/foo/bar/baz", mpoint);
+ int fd = open(foo_bar_baz, O_RDONLY, 0);
+ if (fd >= 0) {
+ read(fd, (char *)buf, 11);
+ close(fd);
+ }
+}
+
+int main(int argc, char *argv[]) {
+ activity(argv[1]);

+Subject: f2fs: fix to do sanity check with reserved blkaddr of inline inode
+
+From: Chao Yu <yuchao0@huawei.com>
+
+[ Upstream commit 4dbe38dc386910c668c75ae616b99b823b59f3eb ]
+
+As Wen Xu reported in bugzilla, after image was injected with random data
+by fuzzing, inline inode would contain invalid reserved blkaddr, then
+during inline conversion, we will encounter illegal memory accessing
+reported by KASAN, the root cause of this is when writing out converted
+inline page, we will use invalid reserved blkaddr to update sit bitmap,
+result in accessing memory beyond sit bitmap boundary.
+
+In order to fix this issue, let's do sanity check with reserved block
+address of inline inode to avoid above condition.

+Subject: f2fs: fix to propagate return value of scan_nat_page()
+
+From: Chao Yu <yuchao0@huawei.com>
+
+[ Upstream commit e2374015f27fe5ee5d5c37966e2faf396cdaaa65 ]
+
+As Anatoly Trosinenko reported in bugzilla:
+
+How to reproduce:
+1. Compile the 73fcb1a370c76 version of the kernel using the config attached
+2. Unpack and mount the attached filesystem image as F2FS
+3. The kernel will BUG() on mount (BUGs are explicitly enabled in config)

+
+During loading NAT entries, we will do sanity check, once the entry info
+is corrupted, it will cause BUG_ON directly to protect user data from
+being overwrited.
+
+In this case, it will be better to just return failure on mount() instead
+of panic, so that user can get hint from kmsg and try fsck for recovery
+immediately rather than after an abnormal reboot.

+If segment type in SSA and SIT is inconsistent, we will encounter below
+BUG_ON during GC, to avoid this panic, let's just skip doing GC on such
+segment.

+Subject: f2fs: issue discard align to section in LFS mode
+
+From: Yunlong Song <yunlong.song@huawei.com>
+
+[ Upstream commit ad6672bbc527727dc8968e8d92687f55ae928ce5 ]
+
+For the case when sbi->segs_per_sec > 1 with lfs mode, take
+section:segment = 5 for example, if the section prefree_map is
+...previous section | current section (1 1 0 1 1) | next section...,
+then the start = x, end = x + 1, after start = start_segno +
+sbi->segs_per_sec, start = x + 5, then it will skip x + 3 and x + 4, but
+their bitmap is still set, which will cause duplicated
+f2fs_issue_discard of this same section in the next write_checkpoint:
+
+round 1: section bitmap : 1 1 1 1 1, all valid, prefree_map: 0 0 0 0 0
+then rm data block NO.2, block NO.2 becomes invalid, prefree_map: 0 0 1 0 0
+write_checkpoint: section bitmap: 1 1 0 1 1, prefree_map: 0 0 0 0 0,
+prefree of NO.2 is cleared, and no discard issued
+
+round 2: rm data block NO.0, NO.1, NO.3, NO.4
+all invalid, but prefree bit of NO.2 is set and cleared in round 1, then
+prefree_map: 1 1 0 1 1
+write_checkpoint: section bitmap: 0 0 0 0 0, prefree_map: 0 0 0 1 1, no
+valid blocks of this section, so discard issued, but this time prefree
+bit of NO.3 and NO.4 is skipped due to start = start_segno + sbi->segs_per_sec;
+
+round 3:
+write_checkpoint: section bitmap: 0 0 0 0 0, prefree_map: 0 0 0 1 1 ->
+0 0 0 0 0, no valid blocks of this section, so discard issued,
+this time prefree bit of NO.3 and NO.4 is cleared, but the discard of
+this section is sent again...
+
+To fix this problem, we can align the start and end value to section
+boundary for fstrim and real-time discard operation, and decide to issue
+discard only when the whole section is invalid, which can issue discard
+aligned to section size as much as possible and avoid redundant discard.

+
+From: Daniel Mack <daniel@zonque.org>
+
+[ Upstream commit 9dabfdd84bdfa25f0df486dd3de43e53e79a1892 ]
+
+The pxa3xx driver uses the pinctrl-single driver since a while which
+does not implement a .gpio_set_direction() callback. The pinmux core
+will simply return 0 in this case, and the pxa3xx gpio driver hence
+believes the pinctrl driver did its job and returns as well.
+
+This effectively makes pxa_gpio_direction_{input,output} no-ops.
+
+To fix this, do not call into the pinctrl subsystem for the PXA3xx
+platform for now. We can revert this once the pinctrl-single driver
+learned to support setting pin directions.

+Subject: gpio: tegra: Move driver registration to subsys_init level
+
+From: Dmitry Osipenko <digetx@gmail.com>
+
+[ Upstream commit 40b25bce0adbe641a744d1291bc0e51fb7f3c3d8 ]
+
+There is a bug in regards to deferred probing within the drivers core
+that causes GPIO-driver to suspend after its users. The bug appears if
+GPIO-driver probe is getting deferred, which happens after introducing
+dependency on PINCTRL-driver for the GPIO-driver by defining "gpio-ranges"
+property in device-tree. The bug in the drivers core is old (more than 4
+years now) and is well known, unfortunately there is no easy fix for it.
+The good news is that we can workaround the deferred probe issue by
+changing GPIO / PINCTRL drivers registration order and hence by moving
+PINCTRL driver registration to the arch_init level and GPIO to the
+subsys_init.

+
+From: Denis Drozdov <denisd@mellanox.com>
+
+[ Upstream commit 75da96067ade4e7854379ec2f7834f3497652b1a ]
+
+The change of ipoib_ah data structure with adding "valid" flag and
+checks of ah->valid in ipoib_start_xmit affected multicast packet flow.
+
+Since the multicast flow doesn't invoke path_rec_start, "ah->valid" flag
+remains unset, so that ipoib_start_xmit end up with neigh_refresh_path
+instead of sending the packet using neigh.
+
+"ah->valid" has to be set in multicast send flow. As a result IPoIB
+starts sending packets via neigh immediately and eliminates 60sec delay
+of neigh keep alive interval.
+
+The typical example of this issue are two sequential arpings:
+
+arping 11.134.208.9 -> got response (mcast_send)
+arping 11.134.208.9 -> no response (ah->valid = 0)

+From: Nick Dyer <nick.dyer@itdev.co.uk>
+
+[ Upstream commit 36f5d9ef26e52edff046b4b097855db89bf0cd4a ]
+
+The driver only registers one input device, which uses the screen
+parameters from the first T9 instance. The first T63 instance also uses
+those parameters.
+
+It is incorrect to send input reports from the second instances of these
+objects if they are enabled: the input scaling will be wrong and the
+positions will be mashed together.
+
+This also causes problems on Android if the number of slots exceeds 32.
+
+In the future, this could be handled by looking for enabled touch object
+instances and creating an input device for each one.

+
+From: Will Deacon <will.deacon@arm.com>
+
+[ Upstream commit b63b3439b85609338e4faabd5d2588dbda137e5c ]
+
+If we find that the SMMU is enabled during probe, we reset it by
+re-initialising its registers and either enabling translation or placing
+it into bypass based on the disable_bypass commandline option.
+
+In the case of a kdump kernel, the SMMU won't have been shutdown cleanly
+by the previous kernel and there may be concurrent DMA through the SMMU.
+Rather than reset the SMMU to bypass, which would likely lead to rampant
+data corruption, we can instead configure the SMMU to abort all incoming
+transactions when we find that it is enabled from within a kdump kernel.

+ipmmu_attach_device() takes a spinlock, while arm_lpae_alloc_pgtable()

+
+Fix this by replacing the spinlock by a mutex, like the arm-smmu driver

+Subject: iwlwifi: pcie: don't access periphery registers when not available
+
+From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
+
+[ Upstream commit f98ad635c097c29339b7a7d6947173000485893d ]
+
+The periphery can't be accessed before we set the
+INIT_DONE bit which initializes the device.
+
+A previous patch added a reconfiguration of the MSI-X
+tables upon resume, but at that point in the flow,
+INIT_DONE wasn't set. Since the reconfiguration of the
+MSI-X tables require periphery access, it failed.
+
+The difference between WoWLAN and without WoWLAN is that
+in WoWLAN, iwl_trans_pcie_d3_suspend clears the INIT_DONE
+without clearing the STATUS_DEVICE_ENABLED bit in the
+software status. Because of that, the resume code thinks
+that the device is enabled, but the INIT_DONE bit has been
+cleared.
+
+To fix this, don't reconfigure the MSI-X tables in case
+WoWLAN is enabled. It will be done in
+iwl_trans_pcie_d3_resume anyway.

+Subject: md/raid5: fix data corruption of replacements after originals dropped
+
+From: BingJing Chang <bingjingc@synology.com>
+
+[ Upstream commit d63e2fc804c46e50eee825c5d3a7228e07048b47 ]
+
+During raid5 replacement, the stripes can be marked with R5_NeedReplace
+flag. Data can be read from being-replaced devices and written to
+replacing spares without reading all other devices. (It's 'replace'
+mode. s.replacing = 1) If a being-replaced device is dropped, the
+replacement progress will be interrupted and resumed with pure recovery
+mode. However, existing stripes before being interrupted cannot read
+from the dropped device anymore. It prints lots of WARN_ON messages.
+And it results in data corruption because existing stripes write
+problematic data into its replacement device and update the progress.
+
+\# Erase disks (1MB + 2GB)
+dd if=/dev/zero of=/dev/sda bs=1MB count=2049
+dd if=/dev/zero of=/dev/sdb bs=1MB count=2049
+dd if=/dev/zero of=/dev/sdc bs=1MB count=2049
+dd if=/dev/zero of=/dev/sdd bs=1MB count=2049
+mdadm -C /dev/md0 -amd -R -l5 -n3 -x0 /dev/sd[abc] -z 2097152
+\# Ensure array stores non-zero data
+dd if=/root/data_4GB.iso of=/dev/md0 bs=1MB
+\# Start replacement
+mdadm /dev/md0 -a /dev/sdd
+mdadm /dev/md0 --replace /dev/sda
+
+Then, Hot-plug out /dev/sda during recovery, and wait for recovery done.
+echo check > /sys/block/md0/md/sync_action
+cat /sys/block/md0/md/mismatch_cnt # it will be greater than 0.
+
+Soon after you hot-plug out /dev/sda, you will see many WARN_ON
+messages. The replacement recovery will be interrupted shortly. After
+the recovery finishes, it will result in data corruption.
+
+Actually, it's just an unhandled case of replacement. In commit
+<f94c0b6658c7> (md/raid5: fix interaction of 'replace' and 'recovery'.),
+if a NeedReplace device is not UPTODATE then that is an error, the
+commit just simply print WARN_ON but also mark these corrupted stripes
+with R5_WantReplace. (it means it's ready for writes.)
+
+To fix this case, we can leverage 'sync and replace' mode mentioned in
+commit <9a3e1101b827> (md/raid5: detect and handle replacements during
+recovery.). We can add logics to detect and use 'sync and replace' mode
+for these stripes.

+
+From: Robert Schlabbach <Robert.Schlabbach@gmx.net>
+
+[ Upstream commit 157eb9a0b75e97ad390c6e50c7381b0a0e02fe97 ]
+
+The em28xx driver never touched the EM2874 register bits that control
+the transport stream packet filters, leaving them at whatever default
+the firmware has set. E.g. the Pinnacle 290e disables them by default,
+while the Hauppauge WinTV dualHD enables discarding NULL packets by
+default.
+
+However, some applications require NULL packets, e.g. to determine the
+load in DOCSIS segments, so discarding NULL packets is undesired for
+such applications.
+
+This patch simply extends the bit mask when starting or stopping the
+transport stream packet capture, so that the filter bits are cleared.
+It has been verified that this makes the Hauppauge WinTV dualHD pass
+an unfiltered DVB-C stream including NULL packets, which it didn't
+before.

+Subject: media: em28xx: Fix dual transport stream operation
+
+From: Brad Love <brad@nextdimension.cc>
+
+[ Upstream commit a7853c257a3ea0907467a1750ff45de4d9ba1915 ]
+
+Addresses the following, which introduced a regression itself:
+
+Commit 509f89652f83 ("media: em28xx: fix a regression with HVR-950")
+
+The regression fix breaks dual transport stream support. Currently,
+when a tuner starts streaming it sets alt mode on the USB interface.
+The problem is, in a dual tuner model, both tuners share the same
+USB interface, so when the second tuner becomes active and sets alt
+mode on the interface it kills streaming on the other port.
+
+This patch addresses the regression by only setting alt mode
+on the USB interface during em28xx_start_streaming, if the
+device is not a dual tuner model. This allows all older and
+single tuner devices to explicitly set alt mode during stream
+startup. Testers report both isoc and bulk DualHD models work
+correctly with the alt mode set only once, in em28xx_dvb_init.
+

+
+From: Brad Love <brad@nextdimension.cc>
+
+[ Upstream commit 20cdcaf903298d54b834daedf65a2ddef70cae0a ]
+
+During the duplication of em28xx state for the second tuner pair
+a pointer to alt_max_pkt_size_isoc is copied. During tear down
+the second tuner is destroyed first and kfrees alt_max_pkt_size_isoc,
+then the first tuner is destroyed and kfrees it again. The property
+should only be kfree'd if the tuner is PRIMARY_TS.

+Subject: media: s5p-mfc: Fix buffer look up in s5p_mfc_handle_frame_{new, copy_time} functions
+
+From: Sylwester Nawrocki <s.nawrocki@samsung.com>
+
+[ Upstream commit 4faeaf9c0f4581667ce5826f9c90c4fd463ef086 ]
+
+Look up of buffers in s5p_mfc_handle_frame_new, s5p_mfc_handle_frame_copy_time
+functions is not working properly for DMA addresses above 2 GiB. As a result
+flags and timestamp of returned buffers are not set correctly and it breaks
+operation of GStreamer/OMX plugins which rely on the CAPTURE buffer queue
+flags.
+
+Due to improper return type of the get_dec_y_adr, get_dspl_y_adr callbacks
+and sign bit extension these callbacks return incorrect address values,
+e.g. 0xfffffffffefc0000 instead of 0x00000000fefc0000. Then the statement:
+
+"if (vb2_dma_contig_plane_dma_addr(&dst_buf->b->vb2_buf, 0) == dec_y_addr)"
+
+is always false, which breaks looking up capture queue buffers.
+
+To ensure proper matching by address u32 type is used for the DMA
+addresses. This should work on all related SoCs, since the MFC DMA
+address width is not larger than 32-bit.
+
+Changes done in this patch are minimal as there is a larger patch series
+pending refactoring the whole driver.

+
+From: Andrey Smirnov <andrew.smirnov@gmail.com>
+
+[ Upstream commit 6c450bdf13ebe110821a74960936cec936edae49 ]
+
+Relying on serial port defaults for flow control and parity can result
+in complete breakdown of communication with RAVE SP on some platforms
+where defaults are not what we need them to be. One such case is
+VF610-base ZII SPU3 board (not supported upstream). To avoid this
+problem in the future, add code to explicitly configure both.

+
+From: Paul Burton <paul.burton@mips.com>
+
+[ Upstream commit 0494d7ffdcebc6935410ea0719b24ab626675351 ]
+
+isa_virt_to_bus() & isa_bus_to_virt() claim to treat ISA bus addresses
+as being identical to physical addresses, but they fail to do so in the
+presence of a non-zero PHYS_OFFSET.
+
+Correct this by having them use virt_to_phys() & phys_to_virt(), which
+consolidates the calculations to one place & ensures that ISA bus
+addresses do indeed match physical addresses.

+Subject: net: dcb: For wild-card lookups, use priority -1, not 0
+
+From: Petr Machata <petrm@mellanox.com>
+
+[ Upstream commit 08193d1a893c802c4b807e4d522865061f4e9f4f ]
+
+The function dcb_app_lookup walks the list of specified DCB APP entries,
+looking for one that matches a given criteria: ifindex, selector,
+protocol ID and optionally also priority. The "don't care" value for
+priority is set to 0, because that priority has not been allowed under
+CEE regime, which predates the IEEE standardization.
+
+Under IEEE, 0 is a valid priority number. But because dcb_app_lookup
+considers zero a wild card, attempts to add an APP entry with priority 0
+fail when other entries exist for a given ifindex / selector / PID
+triplet.
+
+Fix by changing the wild-card value to -1.

+
+From: Arun Parameswaran <arun.parameswaran@broadcom.com>
+
+[ Upstream commit 77fefa93bfebe4df44f154f2aa5938e32630d0bf ]
+
+Modify the register offsets in the Broadcom iProc mdio mux to start
+from the top of the register address space.
+
+Earlier, the base address pointed to the end of the block's register
+space. The base address will now point to the start of the mdio's
+address space. The offsets have been fixed to match this.

+
+From: Mauricio Faria de Oliveira <mfo@canonical.com>
+
+[ Upstream commit 14cb2c8a6c5dae57ee3e2da10fa3db2b9087e39e ]
+
+The if-block that sets a successful return value in aix_partition()
+uses 'lvip[].pps_per_lv' and 'n[].name' potentially uninitialized.
+
+For example, if 'numlvs' is zero or alloc_lvn() fails, neither is
+initialized, but are used anyway if alloc_pvd() succeeds after it.
+
+So, make the alloc_pvd() call conditional on their initialization.
+
+This has been hit when attaching an apparently corrupted/stressed
+AIX LUN, misleading the kernel to pr_warn() invalid data and hang.

+Subject: perf build: Fix installation directory for eBPF
+
+From: Thomas Richter <tmricht@linux.ibm.com>
+
+[ Upstream commit 83868bf71d2eb7700b37f1ea188007f0125e4ee4 ]
+
+The perf tool build and install is controlled via a Makefile. The
+'install' rule creates directories and copies files. Among them are
+header files installed in /usr/lib/include/perf/bpf/.
+
+However all listed examples are installing its header files in
+
+ /usr/lib/<tool-name>/...[/include]/header.h
+
+and not in
+
+ /usr/lib/include/<tool-name>/.../header.h.
+
+Background information:
+
+Building the Fedora 28 glibc RPM on s390x and s390 fails on s390 (gcc
+-m31) as gcc is not able to find header-files like stdbool.h.
+
+In the glibc.spec file, you can see that glibc is configured with
+"--with-headers". In this case, first -nostdinc is added to the CFLAGS
+and then further include paths are added via -isystem. One of those
+paths should contain header files like stdbool.h.
+
+In order to get this path, gcc is invoked with:
+
+- on Fedora 28 (with 4.18 kernel):
+
+ $ gcc -print-file-name=include
+ /usr/lib/gcc/s390x-redhat-linux/8/include
+ $ gcc -m31 -print-file-name=include
+ /usr/lib/gcc/s390x-redhat-linux/8/../../../../lib/include
+ => If perf is installed, this is: /usr/lib/include
+ On my machine this directory is only containing the directory "perf".
+ If perf is not installed gcc returns: /usr/lib/gcc/s390x-redhat-linux/8/include
+
+- on Ubuntu 18.04 (with 4.15 kernel):
+
+ $ gcc -print-file-name=include
+ /usr/lib/gcc/s390x-linux-gnu/7/include
+ $ gcc -m31 -print-file-name=include
+ /usr/lib/gcc/s390x-linux-gnu/7/include
+ => gcc returns the correct path even if perf is installed.
+
+In each case, the introduction of the subdirectory /usr/lib/include
+leads to the regression that one can not build the glibc RPM for s390
+anymore as gcc can not find headers like stdbool.h.
+
+To remedy this install bpf.h to /usr/lib/perf/include/bpf/bpf.h
+
+Output before using the command 'perf test -Fv 40':
+
+ echo '...[bpf-program-source]...' | /usr/bin/clang ... \
+ -I/root/lib/include/perf/bpf ...
+ ^^^^^^^^^^^^
+...
+ [root@p23lp27 perf]# perf test -F 40

+ 40.1: Basic BPF filtering : Ok
+ 40.2: BPF pinning : Ok
+ 40.3: BPF prologue generation : Ok

+
+Output after using command 'perf test -Fv 40':
+
+ echo '...[bpf-program-source]...' | /usr/bin/clang ... \

+ 40.4: BPF relocation checker : Ok
+ [root@p23lp27 perf]#
+
+Committer testing:
+
+While the above 'perf test -F 40' (or 'perf test bpf') will allow us
+to see that the correct path is now added via -I, to actually test this
+we better try to use a bpf script that includes files in the changed
+directory.
+
+We have the files that now reside in /root/lib/perf/examples/bpf/ to do
+just that:

+
+'perf c2c' scans read/write accesses and tries to find false sharing

+Subject: perf evlist: Fix error out while applying initial delay and LBR
+
+From: Kan Liang <kan.liang@linux.intel.com>
+
+[ Upstream commit 95035c5e167ae6e740b1ddd30210ae0eaf39a5db ]
+
+'perf record' will error out if both --delay and LBR are applied.
+
+For example:
+
+ # perf record -D 1000 -a -e cycles -j any -- sleep 2
+ Error:
+ dummy:HG: PMU Hardware doesn't support sampling/overflow-interrupts.
+ Try 'perf stat'
+ #
+
+A dummy event is added implicitly for initial delay, which has the same
+configurations as real sampling events. The dummy event is a software
+event. If LBR is configured, perf must error out.
+
+The dummy event will only be used to track PERF_RECORD_MMAP while perf
+waits for the initial delay to enable the real events. The BRANCH_STACK
+bit can be safely cleared for the dummy event.
+
+After applying the patch:
+
+ # perf record -D 1000 -a -e cycles -j any -- sleep 2
+ [ perf record: Woken up 1 times to write data ]
+ [ perf record: Captured and wrote 1.054 MB perf.data (828 samples) ]

+Subject: pinctrl/amd: only handle irq if it is pending and unmasked
+
+From: Daniel Kurtz <djkurtz@chromium.org>
+
+[ Upstream commit 8bbed1eef001fdfc0ee9595f64cc4f769d265af4 ]
+
+The AMD pinctrl driver demultiplexes GPIO interrupts and fires off their
+individual handlers.
+
+If one of these GPIO irqs is configured as a level interrupt, and its
+downstream handler is a threaded ONESHOT interrupt, the GPIO interrupt
+source is masked by handle_level_irq() until the eventual return of the
+threaded irq handler. During this time the level GPIO interrupt status
+will still report as high until the actual gpio source is cleared - both
+in the individual GPIO interrupt status bit (INTERRUPT_STS_OFF) and in
+its corresponding "WAKE_INT_STATUS_REG" bit.
+
+Thus, if another GPIO interrupt occurs during this time,
+amd_gpio_irq_handler() will see that the (masked-and-not-yet-cleared)
+level irq is still pending and incorrectly call its handler again.
+
+To fix this, have amd_gpio_irq_handler() check for both interrupts status
+and mask before calling generic_handle_irq().
+
+Note: Is it possible that this bug was the source of the interrupt storm
+on Ryzen when using chained interrupts before commit ba714a9c1dea85
+("pinctrl/amd: Use regular interrupt instead of chained")?

+Subject: pinctrl: berlin: fix 'pctrl->functions' allocation in berlin_pinctrl_build_state
+
+From: YueHaibing <yuehaibing@huawei.com>
+
+[ Upstream commit b5031b7db77dc47f474f0efc2b2552c32b7bb59d ]
+
+fixes following Smatch static check warning:
+
+ drivers/pinctrl/berlin/berlin.c:237 berlin_pinctrl_build_state()
+ warn: passing devm_ allocated variable to kfree. 'pctrl->functions'
+
+As we will be calling krealloc() on pointer 'pctrl->functions', which means
+kfree() will be called in there, devm_kzalloc() shouldn't be used with
+the allocation in the first place. Fix the warning by calling kcalloc()
+and managing the free procedure in error path on our own.

+User controls @dev_minor which to be used as index of pkt_devs.
+So, It can be exploited via Spectre-like attack. (speculative execution)
+
+This kind of attack leaks address of pkt_devs, [1]
+It leads an attacker to bypass security mechanism such as KASLR.

+
+Indicating that a PUD was being leaked.
+
+However what's really happening is that kmemleak is not able to
+recognise the references from the PGD to the PUD, because they are not
+fully qualified pointers.
+
+We can confirm that in xmon, eg:
+
+Find the task struct for pid 1 "init":
+ 0:mon> P
+ task_struct ->thread.ksp PID PPID S P CMD
+ c0000001fe7c0000 c0000001fe803960 1 0 S 13 systemd
+
+Dump virtual address 0 to find the PGD:
+ 0:mon> dv 0 c0000001fe7c0000
+ pgd @ 0xc0000000f8b01000
+
+Dump the memory of the PGD:
+ 0:mon> d c0000000f8b01000
+ c0000000f8b01000 00000000f8b90000 0000000000000000 |................|
+ c0000000f8b01010 0000000000000000 0000000000000000 |................|
+ c0000000f8b01020 0000000000000000 0000000000000000 |................|
+ c0000000f8b01030 0000000000000000 00000000f8b80000 |................|
+ ^^^^^^^^^^^^^^^^
+
+There we can see the reference to our supposedly leaked PUD. But
+because it's missing the leading 0xc, kmemleak won't recognise it.
+
+We can confirm it's still in use by translating an address that is
+mapped via it:
+ 0:mon> dv 7fff94000000 c0000001fe7c0000
+ pgd @ 0xc0000000f8b01000
+ pgdp @ 0xc0000000f8b01038 = 0x00000000f8b80000 <--
+ pudp @ 0xc0000000f8b81ff8 = 0x00000000037c4000
+ pmdp @ 0xc0000000037c5ca0 = 0x00000000fbd89000
+ ptep @ 0xc0000000fbd89000 = 0xc0800001d5ce0386
+ Maps physical address = 0x00000001d5ce0000
+ Flags = Accessed Dirty Read Write
+
+The fix is fairly simple. We need to tell kmemleak to ignore PUD
+allocations and never report them as leaks. We can also tell it not to
+scan the PGD, because it will never find pointers in there. However it
+will still notice if we allocate a PGD and then leak it.

+Subject: powerpc/powernv: Fix concurrency issue with npu->mmio_atsd_usage
+
+From: Reza Arbab <arbab@linux.ibm.com>
+
+[ Upstream commit 9eab9901b015f489199105c470de1ffc337cfabb ]
+
+We've encountered a performance issue when multiple processors stress
+{get,put}_mmio_atsd_reg(). These functions contend for
+mmio_atsd_usage, an unsigned long used as a bitmask.
+
+The accesses to mmio_atsd_usage are done using test_and_set_bit_lock()
+and clear_bit_unlock(). As implemented, both of these will require
+a (successful) stwcx to that same cache line.
+
+What we end up with is thread A, attempting to unlock, being slowed by
+other threads repeatedly attempting to lock. A's stwcx instructions
+fail and retry because the memory reservation is lost every time a
+different thread beats it to the punch.
+
+There may be a long-term way to fix this at a larger scale, but for
+now resolve the immediate problem by gating our call to
+test_and_set_bit_lock() with one to test_bit(), which is obviously
+implemented without using a store.

+Subject: powerpc/pseries: fix EEH recovery of some IOV devices
+
+From: Sam Bobroff <sbobroff@linux.ibm.com>
+
+[ Upstream commit b87b9cf4935325c98522823caeddd333022a1c62 ]
+
+EEH recovery currently fails on pSeries for some IOV capable PCI
+devices, if CONFIG_PCI_IOV is on and the hypervisor doesn't provide
+certain device tree properties for the device. (Found on an IOV
+capable device using the ipr driver.)
+
+Recovery fails in pci_enable_resources() at the check on r->parent,
+because r->flags is set and r->parent is not. This state is due to
+sriov_init() setting the start, end and flags members of the IOV BARs
+but the parent not being set later in
+pseries_pci_fixup_iov_resources(), because the
+"ibm,open-sriov-vf-bar-info" property is missing.
+
+Correct this by zeroing the resource flags for IOV BARs when they
+can't be configured (this is the same method used by sriov_init() and
+__pci_read_base()).
+
+VFs cleared this way can't be enabled later, because that requires
+another device tree property, "ibm,number-of-configurable-vfs" as well
+as support for the RTAS function "ibm_map_pes". These are all part of
+hypervisor support for IOV and it seems unlikely that a hypervisor
+would ever partially, but not fully, support it. (None are currently
+provided by QEMU/KVM.)

+From: James Smart <jsmart2021@gmail.com>
+
+[ Upstream commit 93a3922da428ec0752e8b2ab00c42dadbbf805a9 ]
+
+During remote port loss fault testing, the driver crashed with the
+following trace:
+
+general protection fault: 0000 [#1] SMP

+ ret_from_fork+0x55/0x80
+
+After registering a new remoteport, the driver is pulling an ndlp pointer
+from the lpfc rport associated with the private area of a newly registered
+remoteport. The private area is uninitialized, so it's garbage.
+
+Correct by pulling the the lpfc rport pointer from the entering ndlp point,
+then ndlp value from at rport. Note the entering ndlp may be replacing by
+the rport->ndlp due to an address change swap.

+This patch prevents a bug where data_bitmap is allocated in

+is mapped to a LUN, then we try to access the data_bitmap based on the new
+max_blocks limit which may now be out of range.

+To prevent this, we just check if data_bitmap has been setup. If it has

+
+[ Upstream commit 0c62f8a820b7fdeacf5ad9f9e24b53043d372c97 ]
+
+Test 6fb4 creates one mirred and one pipe action, but only flushes mirred
+on teardown. Leaking pipe action causes failures in other tests.
+
+Add additional teardown command to also flush gact actions.

+From: Simon Horman <horms+renesas@verge.net.au>
+
+[ Upstream commit 542cdf4068049458e1411b120bd5a4bbe3ddc49a ]
+
+Ensure that the base address used by a call to rcar_thermal_common_write()
+may be NULL if the SOC supports interrupts for use with the thermal device
+but none are defined in DT as is the case for R-Car H1 (r8a7779). Guard
+against this condition to prevent a NULL dereference when the device is
+probed.
+
+Tested on:
+* R-Mobile APE6 (r8a73a4) / APE6EVM
+* R-Car H1 (r8a7779) / Marzen
+* R-Car H2 (r8a7790) / Lager
+* R-Car M2-W (r8a7791) / Koelsch
+* R-Car M2-N (r8a7793) / Gose
+* R-Car D3 ES1.0 (r8a77995) / Draak

+Clearly, __hwmon_device_register is unhappy about the property name.
+Some investigation reveals that thermal_add_hwmon_sysfs doesn't
+sanitize the name of the attribute.
+
+In order to keep it quiet, let's replace '-' with '_' in hwmon->type

+Subject: timers: Clear timer_base::must_forward_clk with timer_base::lock held
+
+From: Gaurav Kohli <gkohli@codeaurora.org>
+
+[ Upstream commit 363e934d8811d799c88faffc5bfca782fd728334 ]
+
+timer_base::must_forward_clock is indicating that the base clock might be
+stale due to a long idle sleep.
+
+The forwarding of the base clock takes place in the timer softirq or when a
+timer is enqueued to a base which is idle. If the enqueue of timer to an
+idle base happens from a remote CPU, then the following race can happen:
+
+ CPU0 CPU1
+ run_timer_softirq mod_timer
+
+ base = lock_timer_base(timer);
+ base->must_forward_clk = false
+ if (base->must_forward_clk)
+ forward(base); -> skipped
+
+ enqueue_timer(base, timer, idx);
+ -> idx is calculated high due to
+ stale base
+ unlock_timer_base(timer);
+ base = lock_timer_base(timer);
+ forward(base);
+
+The root cause is that timer_base::must_forward_clk is cleared outside the
+timer_base::lock held region, so the remote queuing CPU observes it as
+cleared, but the base clock is still stale. This can cause large
+granularity values for timers, i.e. the accuracy of the expiry time
+suffers.
+
+Prevent this by clearing the flag with timer_base::lock held, so that the
+forwarding takes place before the cleared flag is observable by a remote
+CPU.

+Subject: tools/testing/nvdimm: kaddr and pfn can be NULL to ->direct_access()
+
+From: Huaisheng Ye <yehs1@lenovo.com>
+
+[ Upstream commit 45df5d3dc0c7289c1e67afe6d2ba806ad5174314 ]
+
+The mock / test version of pmem_direct_access() needs to check the
+validity of pointers kaddr and pfn for NULL assignment. If anyone
+equals to NULL, it doesn't need to calculate the value.
+
+If pointer equals to NULL, that is to say callers may have no need for
+kaddr or pfn, so this patch is prepared for allowing them to pass in
+NULL instead of having to pass in a local pointer or variable that
+they then just throw away.

+

+
+An SPI TPM device managed directly on an embedded board using

+pass the IRQn from the TPM device associated with the SPI
+device. This is already handled by the SPI core, so make sure
+to pass this down to the core as well.

+(The TPM core habit of using -1 to signal no IRQ is dubious

+The uio_unregister_device() function assumes that if "info->uio_dev" is
+non-NULL that means "info" is fully allocated. Setting info->uio_de
+has to be the last thing in the function.
+
+In the current code, if request_threaded_irq() fails then we return with

+
+From: Joerg Roedel <jroedel@suse.de>
+
+[ Upstream commit ca38dc8f2724d101038b1205122c93a1c7f38f11 ]
+
+Fuzzing the PTI-x86-32 code with trinity showed unhandled
+kernel paging request oops-messages that looked a lot like
+silent data corruption.
+
+Lot's of debugging and testing lead to the kexec-32bit code,
+which is still allocating 4k PGDs when PTI is enabled. But
+since it uses native_set_pud() to build the page-table, it
+will unevitably call into __pti_set_user_pgtbl(), which
+writes beyond the allocated 4k page.
+
+Use PGD_ALLOCATION_ORDER to allocate PGDs in the kexec code
+to fix the issue.

+Subject: x86/mm: Remove in_nmi() warning from vmalloc_fault()
+
+From: Joerg Roedel <jroedel@suse.de>
+
+[ Upstream commit 6863ea0cda8725072522cd78bda332d9a0b73150 ]
+
+It is perfectly okay to take page-faults, especially on the
+vmalloc area while executing an NMI handler. Remove the
+warning.
