5865985416 smb3: extend fscache mount volume coherency check
It is better to check volume id and creation time, not just
the root inode number to verify if the volume has changed
when remounting.

Pull AFS updates from David Howells:
 "There's some core VFS changes which affect a couple of filesystems:

   - Make the inode hash table RCU safe and providing some RCU-safe
     accessor functions. The search can then be done without taking the
     inode_hash_lock. Care must be taken because the object may be being
     deleted and no wait is made.

   - Allow iunique() to avoid taking the inode_hash_lock.

   - Allow AFS's callback processing to avoid taking the inode_hash_lock
     when using the inode table to find an inode to notify.

   - Improve Ext4's time updating. Konstantin Khlebnikov said "For now,
     I've plugged this issue with try-lock in ext4 lazy time update.
     This solution is much better."

  Then there's a set of changes to make a number of improvements to the
  AFS driver:

   - Improve callback (ie. third party change notification) processing
     by:

      (a) Relying more on the fact we're doing this under RCU and by
          using fewer locks. This makes use of the RCU-based inode
          searching outlined above.

      (b) Moving to keeping volumes in a tree indexed by volume ID
          rather than a flat list.

      (c) Making the server and volume records logically part of the
          cell. This means that a server record now points directly at
          the cell and the tree of volumes is there. This removes an N:M
          mapping table, simplifying things.

   - Improve keeping NAT or firewall channels open for the server
     callbacks to reach the client by actively polling the fileserver on
     a timed basis, instead of only doing it when we have an operation
     to process.

   - Improving detection of delayed or lost callbacks by including the
     parent directory in the list of file IDs to be queried when doing a
     bulk status fetch from lookup. We can then check to see if our copy
     of the directory has changed under us without us getting notified.

   - Determine aliasing of cells (such as a cell that is pointed to be a
     DNS alias). This allows us to avoid having ambiguity due to
     apparently different cells using the same volume and file servers.

   - Improve the fileserver rotation to do more probing when it detects
     that all of the addresses to a server are listed as non-responsive.
     It's possible that an address that previously stopped responding
     has become responsive again.

  Beyond that, lay some foundations for making some calls asynchronous:

   - Turn the fileserver cursor struct into a general operation struct
     and hang the parameters off of that rather than keeping them in
     local variables and hang results off of that rather than the call
     struct.

   - Implement some general operation handling code and simplify the
     callers of operations that affect a volume or a volume component
     (such as a file). Most of the operation is now done by core code.

   - Operations are supplied with a table of operations to issue
     different variants of RPCs and to manage the completion, where all
     the required data is held in the operation object, thereby allowing
     these to be called from a workqueue.

   - Put the standard "if (begin), while(select), call op, end" sequence
     into a canned function that just emulates the current behaviour for
     now.

  There are also some fixes interspersed:

   - Don't let the EACCES from ICMP6 mapping reach the user as such,
     since it's confusing as to whether it's a filesystem error. Convert
     it to EHOSTUNREACH.

   - Don't use the epoch value acquired through probing a server. If we
     have two servers with the same UUID but in different cells, it's
     hard to draw conclusions from them having different epoch values.

   - Don't interpret the argument to the CB.ProbeUuid RPC as a
     fileserver UUID and look up a fileserver from it.

   - Deal with servers in different cells having the same UUIDs. In the
     event that a CB.InitCallBackState3 RPC is received, we have to
     break the callback promises for every server record matching that
     UUID.

   - Don't let afs_statfs return values that go below 0.

   - Don't use running fileserver probe state to make server selection
     and address selection decisions on. Only make decisions on final
     state as the running state is cleared at the start of probing"

b25c6644bf - Largest change for this cycle is the DM zoned target's metadata
version 2 feature that adds support for pairing regular block
   devices with a zoned device to ease performance impact associated
   with finite random zones of zoned device.  Changes came in 3
   batches: first prepared for and then added the ability to pair a
   single regular block device, second was a batch of fixes to improve
   zoned's reclaim heuristic, third removed the limitation of only
   adding a single additional regular block device to allow many
   devices.  Testing has shown linear scaling as more devices are
   added.
 
 - Add new emulated block size (ebs) target that emulates a smaller
   logical_block_size than a block device supports.  Primary use-case
   is to emulate "512e" devices that have 512 byte logical_block_size
   and 4KB physical_block_size.  This is useful to some legacy
   applications otherwise wouldn't be ablee to be used on 4K devices
   because they depend on issuing IO in 512 byte granularity.
 
 - Add discard interfaces to DM bufio.  First consumer of the interface
   is the dm-ebs target that makes heavy use of dm-bufio.
 
 - Fix DM crypt's block queue_limits stacking to not truncate
   logic_block_size.
 
 - Add Documentation for DM integrity's status line.
 
 - Switch DMDEBUG from a compile time config option to instead use
   dynamic debug via pr_debug.
 
 - Fix DM multipath target's hueristic for how it manages
   "queue_if_no_path" state internally.  DM multipath now avoids
   disabling "queue_if_no_path" unless it is actually needed (e.g. in
   response to configure timeout or explicit "fail_if_no_path"
   message).  This fixes reports of spurious -EIO being reported back
   to userspace application during fault tolerance testing with an NVMe
   backend.  Added various dynamic DMDEBUG messages to assist with
   debugging queue_if_no_path in the future.
 
 - Add a new DM multipath "Historical Service Time" Path Selector.
 
 - Fix DM multipath's dm_blk_ioctl() to switch paths on IO error.
 
 - Improve DM writecache target performance by using explicit
   cache flushing for target's single-threaded usecase and a small
   cleanup to remove unnecessary test in persistent_memory_claim.
 
 - Other small cleanups in DM core, dm-persistent-data, and DM integrity.

 "A more active cycle than most of the recent past, with a few large,
  long discussed works this time.

  The RNBD block driver has been posted for nearly two years now, and
  flowing through RDMA due to it also introducing a new ULP.

  The removal of FMR has been a recurring discussion theme for a long
  time.

  And the usual smattering of features and bug fixes.

3f7e82379f This is the bulk of GPIO changes for the v5.8 kernel cycle.
Core changes:
 
 - A new GPIO aggregator driver has been merged: this can
   join a few select GPIO lines into a new aggregated GPIO
   chip. This can be used for security: a process can be
   granted access to only these lines, for example for
   industrial control. Another way to use this is to
   reexpose certain select lines to a virtual machine or
   container.
 
 - Warn if the gpio-line-names is too long in he DT parser
   core.
 
 - GPIO lines can now be looked up by line name in addition
   to being looked up by offset.
 
 New drivers:
 
 - A new generic regmap GPIO driver has been merged. Too
   many regmap drivers are starting to look like each other
   so we need to create some common ground and try to move
   drivers over to using that.
 
 - The F7188X driver now supports F81865.
 
 Driver improvements:
 
 - Large improvements to the PCA953x expander, get multiple lines
   and several cleanups.
 
 - Large improvements to the DesignWare DWAPB driver, and Sergey
   Semin has volunteered to maintain it.
 
 - PL061 can now be built as a module, this is part of a bigger
   effort to make the ARM platforms more modular.

553ec94cb4 dm mpath: restrict queue_if_no_path state machine
Do not allow saving disabled queue_if_no_path if already saved as
enabled; implies multiple suspends (which shouldn't ever happen).  Log
if this unlikely scenario is ever triggered.

Also, only write MPATHF_SAVED_QUEUE_IF_NO_PATH during presuspend or if
"fail_if_no_path" message.  MPATHF_SAVED_QUEUE_IF_NO_PATH is no longer
always modified, e.g.: even if queue_if_no_path()'s save_old_value
argument wasn't set.  This just implies a bit tighter control over
the management of MPATHF_SAVED_QUEUE_IF_NO_PATH.  Side-effect is
multipath_resume() doesn't reset MPATHF_QUEUE_IF_NO_PATH unless
MPATHF_SAVED_QUEUE_IF_NO_PATH was set (during presuspend); and at that
time the MPATHF_SAVED_QUEUE_IF_NO_PATH bit gets cleared.  So
MPATHF_SAVED_QUEUE_IF_NO_PATH's use is much more narrow in scope.

Last, but not least, do _not_ disable queue_if_no_path during noflush
suspend.  There is no need/benefit to saving off queue_if_no_path via
MPATHF_SAVED_QUEUE_IF_NO_PATH and clearing MPATHF_QUEUE_IF_NO_PATH for
noflush suspend -- by avoiding this needless queue_if_no_path flag
churn there is less potential for MPATHF_QUEUE_IF_NO_PATH to get lost.
Which avoids potential for IOs to be errored back up to userspace
during DM multipath's handling of path failures.

That said, this last change papers over a reported issue concerning
request-based dm-multipath's interaction with blk-mq, relative to
suspend and resume: multipath_endio is being called _before_
multipath_resume.  This should never happen if DM suspend's
blk_mq_quiesce_queue() + dm_wait_for_completion() is genuinely waiting
for all inflight blk-mq requests to complete.  Similarly:
drivers/md/dm.c:__dm_resume() clearly calls dm_table_resume_targets()
_before_ dm_start_queue()'s blk_mq_unquiesce_queue() is called.  If
the queue isn't even restarted until after multipath_resume(); the BIG
question that still needs answering is: how can multipath_end_io beat
multipath_resume in a race!?

a862e4e215 dm mpath: simplify __must_push_back
Remove micro-optimization that infers device is between presuspend and
resume (was done purely to avoid call to dm_noflush_suspending, which
isn't expensive anyway).

Remove flags argument since they are no longer checked.

And remove must_push_back_bio() since it was simply a call to
__must_push_back().

694b5a5d31 ARM: SoC changes for v5.8
One new platform gets added, the Realtek RTD1195, which is an older
 Cortex-a7 based relative of the RTD12xx chips that are already supported
 in arch/arm64. The platform may also be extended to support running
 32-bit kernels on those 64-bit chips for memory-constrained machines.
 
 In the Renesas shmobile platform, we gain support for "RZ/G1H" or R8A7742,
 an eight-core chip based on Cortex-A15 and Cortex-A7 cores, originally
 released in 2016 as one of the last high-end 32-bit designs.
 
 There is ongoing cleanup for the integrator, tegra, imx, and omap2
 platforms, with integrator getting very close to the goal of having
 zero code in arch/arm/, and omap2 moving more of the chip specifics
 from old board code into device tree files.
 
 The Versatile Express platform is made more modular, with built-in
 drivers now becoming loadable modules. This is part of a greater effort
 for the Android OS to have a common kernel binary for all platforms and
 any platform specific code in loadable modules.
 
 The PXA platform drops support for Compulab's pxa2xx boards that had
 rather unusual flash and PCI drivers but no known users remaining.
 All device drivers specific to those boards can now get removed as
 well.
 
 Across platforms, there is ongoing cleanup, with Geert and Rob
 revisiting some a lot of Kconfig options.

Merge tag 'arm-soc-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC updates from Arnd Bergmann:
 "One new platform gets added, the Realtek RTD1195, which is an older
  Cortex-a7 based relative of the RTD12xx chips that are already
  supported in arch/arm64. The platform may also be extended to support
  running 32-bit kernels on those 64-bit chips for memory-constrained
  machines.

  In the Renesas shmobile platform, we gain support for "RZ/G1H" or
  R8A7742, an eight-core chip based on Cortex-A15 and Cortex-A7 cores,
  originally released in 2016 as one of the last high-end 32-bit
  designs.

  There is ongoing cleanup for the integrator, tegra, imx, and omap2
  platforms, with integrator getting very close to the goal of having
  zero code in arch/arm/, and omap2 moving more of the chip specifics
  from old board code into device tree files.

  The Versatile Express platform is made more modular, with built-in
  drivers now becoming loadable modules. This is part of a greater
  effort for the Android OS to have a common kernel binary for all
  platforms and any platform specific code in loadable modules.

  The PXA platform drops support for Compulab's pxa2xx boards that had
  rather unusual flash and PCI drivers but no known users remaining. All
  device drivers specific to those boards can now get removed as well.

  Across platforms, there is ongoing cleanup, with Geert and Rob
  revisiting some a lot of Kconfig options"

587f17018a Kconfig: add config option for asm goto w/ outputs
This allows C code to make use of compilers with support for output
variables along the fallthrough path via preprocessor define:

  CONFIG_CC_HAS_ASM_GOTO_OUTPUT

[ This is not used anywhere yet, and currently released compilers don't
  support this yet, but it's coming, and I have some local experimental
  patches to take advantage of it when it does   - Linus ]

for the ubsan helpers:

Change the Linux implementation to match these, using a local typed
pointer.
