Pull xfs updates from Darrick Wong:
 "In this release we add the ability to set a 'needsrepair' flag
  indicating that we /know/ the filesystem requires xfs_repair, but
  other than that, it's the usual strengthening of metadata validation
  and miscellaneous cleanups.

  Summary:

   - Introduce a "needsrepair" "feature" to flag a filesystem as needing
     a pass through xfs_repair. This is key to enabling filesystem
     upgrades (in xfs_db) that require xfs_repair to make minor
     adjustments to metadata.

   - Refactor parameter checking of recovered log intent items so that
     we actually use the same validation code as them that generate the
     intent items.

   - Various fixes to online scrub not reacting correctly to directory
     entries pointing to inodes that cannot be igetted.

   - Refactor validation helpers for data and rt volume extents.

   - Refactor XFS_TRANS_DQ_DIRTY out of existence.

   - Fix a longstanding bug where mounting with "uqnoenforce" would
     start user quotas in non-enforcing mode but /proc/mounts would
     display "usrquota", implying that they are being enforced.

   - Don't flag dax+reflink inodes as corruption since that is a valid
     (but not fully functional) combination right now.

   - Clean up raid stripe validation functions.

   - Refactor the inode allocation code to be more straightforward.

   - Small prep cleanup for idmapping support.

   - Get rid of the xfs_buf_t typedef"

   - Support for the contiguous memory allocator.

   - Support for IRQ Time Accounting

   - Support for stack tracing

   - Support for strict /dev/mem

   - Support for kernel section protection

  I'm being a bit conservative on the cutoff for this round due to the
  timing, so this is all the new development I'm going to take for this
  cycle (even if some of it probably normally would have been OK). There
  are, however, some fixes on the list that I will likely be sending
  along either later this week or early next week.

  There is one issue in here: one of my test configurations
  (PREEMPT{,_DEBUG}=y) fails to boot on QEMU 5.0.0 (from April) as of
  the .text.init alignment patch.

  With any luck we'll sort out the issue, but given how many bugs get
  fixed all over the place and how unrelated those features seem my
  guess is that we're just running into something that's been lurking
  for a while and has already been fixed in the newer QEMU (though I
  wouldn't be surprised if it's one of these implicit assumptions we
  have in the boot flow). If it was hardware I'd be strongly inclined to
  look more closely, but given that users can upgrade their simulators
  I'm less worried about it"

(cherry picked from commit 83dbd74f)
Signed-off-by: Jani Nikula <jani.nikula@intel.com>

When inserting a VMA, we restrict the placement to the low 4G unless the
caller opts into using the full range. This was done to allow usersapce
the opportunity to transition slowly from a 32b address space, and to
avoid breaking inherent 32b assumptions of some commands.

However, for insert we limited ourselves to 4G-4K, but on verification
we allowed the full 4G. This causes some attempts to bind a new buffer
to sporadically fail with -ENOSPC, but at other times be bound
successfully.

commit 48ea1e32 ("drm/i915/gen9: Set PIN_ZONE_4G end to 4GB - 1
page") suggests that there is a genuine problem with stateless addressing
that cannot utilize the last page in 4G and so we purposefully excluded
it. This means that the quick pin pass may cause us to utilize a buggy
placement.

Pull GPIO updates from Linus Walleij:
 "This is the bulk of the GPIO changes for the v5.11 kernel cycle:

  Core changes:

   - Retired the old set-up function for GPIO IRQ chips. All chips now
     use the template struct gpio_irq_chip and pass that to the core to
     be set up alongside the gpio_chip. We can finally get rid of the
     old cruft.

   - Some refactoring and clean up of the core code.

   - Support edge event timestamps to be stamped using REALTIME (wall
     clock) timestamps. We have found solid use cases for this, so we
     support it.

  New drivers:

   - MStar MSC313 GPIO driver.

   - HiSilicon GPIO driver.

  Driver improvements:

   - The PCA953x driver now also supports the NXP PCAL9554B/C chips.

   - The mockup driver can now be probed from the device tree which is
     pretty useful for virtual prototyping of devices.

   - The Rcar driver now supports .get_multiple()

   - The MXC driver dropped some legacy and became a pure device tree
     client.

   - The Exar driver was moved over to the IDA interface for
     enumerating, and also switched over to using regmap for register
     access"

  client on server address or export or network changes. This can be
  useful for example in order to be notified before the failure - when a
  server's IP address changes (in the future it will allow us to support
  server notifications of when a share is moved).

Pull tracing updates from Steven Rostedt:
 "The major update to this release is that there's a new arch config
  option called CONFIG_HAVE_DYNAMIC_FTRACE_WITH_ARGS.

  Currently, only x86_64 enables it. All the ftrace callbacks now take a
  struct ftrace_regs instead of a struct pt_regs. If the architecture
  has HAVE_DYNAMIC_FTRACE_WITH_ARGS enabled, then the ftrace_regs will
  have enough information to read the arguments of the function being
  traced, as well as access to the stack pointer.

  This way, if a user (like live kernel patching) only cares about the
  arguments, then it can avoid using the heavier weight "regs" callback,
  that puts in enough information in the struct ftrace_regs to simulate
  a breakpoint exception (needed for kprobes).

  A new config option that audits the timestamps of the ftrace ring
  buffer at most every event recorded.

  Ftrace recursion protection has been cleaned up to move the protection
  to the callback itself (this saves on an extra function call for those
  callbacks).

  Perf now handles its own RCU protection and does not depend on ftrace
  to do it for it (saving on that extra function call).

  New debug option to add "recursed_functions" file to tracefs that
  lists all the places that triggered the recursion protection of the
  function tracer. This will show where things need to be fixed as
  recursion slows down the function tracer.

  The eval enum mapping updates done at boot up are now offloaded to a
  work queue, as it caused a noticeable pause on slow embedded boards.

  Various clean ups and last minute fixes"

Pull modules updates from Jessica Yu:
 "Summary of modules changes for the 5.11 merge window:

   - Fix a race condition between systemd/udev and the module loader.

     The module loader was sending a uevent before the module was fully
     initialized (i.e., before its init function has been called). This
     means udev can start processing the module uevent before the module
     has finished initializing, and some udev rules expect that the
     module has initialized already upon receiving the uevent.

     This resulted in some systemd mount units failing if udev processes
     the event faster than the module can finish init. This is fixed by
     delaying the uevent until after the module has called its init
     routine.

   - Make the linker array sections for kernel params and module version
     attributes more robust by switching to use the alignment of the
     type in question.

     Namely, linker section arrays will be constructed using the
     alignment required by the struct (using __alignof__()) as opposed
     to a specific value such as sizeof(void *) or sizeof(long). This is
     less likely to cause breakages should the size of the type ever
     change (Johan Hovold)

   - Fix module state inconsistency by setting it back to GOING when a
     module fails to load and is on its way out (Miroslav Benes)

Pull overlayfs updates from Miklos Szeredi:

 - Allow unprivileged mounting in a user namespace.

   For quite some time the security model of overlayfs has been that
   operations on underlying layers shall be performed with the
   privileges of the mounting task.

   This way an unprvileged user cannot gain privileges by the act of
   mounting an overlayfs instance. A full audit of all function calls
   made by the overlayfs code has been performed to see whether they
   conform to this model, and this branch contains some fixes in this
   regard.

   UUID verification.

 "In this round, we've made more work into per-file compression support.

  For example, F2FS_IOC_GET | SET_COMPRESS_OPTION provides a way to
  change the algorithm or cluster size per file. F2FS_IOC_COMPRESS |
  DECOMPRESS_FILE provides a way to compress and decompress the existing
  normal files manually.

  There is also a new mount option, compress_mode=fs|user, which can
  control who compresses the data.

  Chao also added a checksum feature with a mount option so that
  we are able to detect any corrupted cluster.

  In addition, Daniel contributed casefolding with encryption patch,
  which will be used for Android devices.

  Summary:

  Enhancements:
   - add ioctls and mount option to manage per-file compression feature
   - support casefolding with encryption
   - support checksum for compressed cluster
   - avoid IO starvation by replacing mutex with rwsem
   - add sysfs, max_io_bytes, to control max bio size

  Bug fixes:
   - fix use-after-free issue when compression and fsverity are enabled
   - fix consistency corruption during fault injection test
   - fix data offset for lseek
   - get rid of buffer_head which has 32bits limit in fiemap

The indirect block cleanup may cause control messages to be sent
if offloaded flows are present. However, by the time the flower app
cleanup callback is called txbufs are no longer available and attempts
to send control messages result in a NULL-pointer dereference in
nfp_ctrl_tx_one().

This problem may be resolved by moving the indirect block cleanup
to the stop callback, where txbufs are still available.

As suggested by Jakub Kicinski and Louis Peens.

When multiple subflows are active, we can receive a
window update on subflow with no write space available.
MPTCP will try to push frames on such subflow and will
fail. Pending frames will be pushed only after receiving
a window update on a subflow with some wspace available.

Overall the above could lead to suboptimal aggregate
bandwidth usage.

Instead, we should try to push pending frames as soon as
the subflow reaches both conditions mentioned above.

We can finally enable self-tests with asymmetric links,
as the above makes them finally pass.
