+From: Takashi Iwai <tiwai@suse.de>
+
+[ Upstream commit a91a0e774984aa57090c39dc3269a812417737ed ]
+
+asihpi driver treats -1 as an own invalid PCM format, but this needs
+a proper cast with __force prefix since PCM format type is __bitwise.
+Define a constant with the proper type and use it allover.
+
+This fixes sparse warnings like:

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

+to transition to low power mode in systems with SLP_S0 aka modern

+
+Here driver is trying to do read-modify-write the devslp register. But
+not resetting the bits for which this driver will modify values (DITO,
+MDAT and DETO). So simply reset those bits before updating to new values.

+
+[ 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.

+Subject: ethtool: Remove trailing semicolon for static inline
+
+From: Florian Fainelli <f.fainelli@gmail.com>
+
+[ Upstream commit d89d41556141a527030a15233135ba622ba3350d ]
+
+Android's header sanitization tool chokes on static inline functions having a
+trailing semicolon, leading to an incorrectly parsed header file. While the
+tool should obviously be fixed, also fix the header files for the two affected
+functions: ethtool_get_flow_spec_ring() and ethtool_get_flow_spec_ring_vf().

+Subject: f2fs: do not set free of current section
+
+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.

+
+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.

+Subject: Input: atmel_mxt_ts - only use first T9 instance
+
+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.

+
+[ Upstream commit 46583e8c48c5a094ba28060615b3a7c8c576690f ]
+
+When attaching a device to an IOMMU group with
+CONFIG_DEBUG_ATOMIC_SLEEP=y:
+
+ BUG: sleeping function called from invalid context at mm/slab.h:421

+
+ipmmu_attach_device() takes a spinlock, while arm_lpae_alloc_pgtable()
+allocates memory using GFP_KERNEL. Originally, the ipmmu-vmsa driver
+had its own custom page table allocation implementation using
+GFP_ATOMIC, hence the spinlock was fine.
+
+Fix this by replacing the spinlock by a mutex, like the arm-smmu driver
+does.

+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.

+Subject: MIPS: Fix ISA virt/bus conversion for non-zero PHYS_OFFSET
+
+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.

+
+[ 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

+
+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.

+
+From: Parav Pandit <parav@mellanox.com>
+
+[ Upstream commit 643d213a9a034fa04f5575a40dfc8548e33ce04f ]
+
+Currently if the cm_id is not bound to any netdevice, than for such cm_id,
+net namespace is ignored; which is incorrect.
+
+Regardless of cm_id bound to a netdevice or not, net namespace must
+match. When a cm_id is bound to a netdevice, in such case net namespace
+and netdevice both must match.

+From: Anton Vasilyev <vasilyev@ispras.ru>

+From: Dan Carpenter <dan.carpenter@oracle.com>
+
+[ Upstream commit f019f07ecf6a6b8bd6d7853bce70925d90af02d1 ]
+
+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
+info->uio_dev set to non-NULL but info is not fully allocated and it can
+lead to double frees.

+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.
