Pull device mapper updates from Mike Snitzer:

 - Enable DM core bioset's per-cpu bio cache if QUEUE_FLAG_POLL set.
   This change improves DM's hipri bio polling (REQ_POLLED) performance
   by 7 - 20% depending on the system.

 - Update DM core to use jump_labels to further reduce cost of unlikely
   branches for zoned block devices, dm-stats and swap_bios throttling.

 - Various DM core changes to reduce bio-based DM overhead and simplify
   IO accounting.

 - Fundamental DM core improvements to dm_io reference counting and the
   elimination of using bio_split()+bio_chain() -- instead DM's
   bio-based IO accounting is updated to account that a split occurred.

 - Improve DM core's abnormal bio processing to do less work.

 - Improve DM core's hipri polling support to use a single list rather
   than an hlist.

 - Update DM core to pass NULL bdev to bio_alloc_clone() so that
   initialization that isn't useful for DM can be elided.

 - Add cond_resched to DM stats' various loops that loop over all
   entries.

 - Fix incorrect error code return from DM integrity's constructor.

 - Make DM crypt's printing of the key constant-time.

 - Update bio-based DM multipath to provide high-resolution timer to the
   Historical Service Time (HST) path selector.

Pull nfsd updates from Chuck Lever:
 "We introduce 'courteous server' in this release. Previously NFSD would
  purge open and lock state for an unresponsive client after one lease
  period (typically 90 seconds). Now, after one lease period, another
  client can open and lock those files and the unresponsive client's
  lease is purged; otherwise if the unresponsive client's open and lock
  state is uncontended, the server retains that open and lock state for
  up to 24 hours, allowing the client's workload to resume after a
  lengthy network partition.

  A longstanding issue with NFSv4 file creation is also addressed.
  Previously a file creation can fail internally, returning an error to
  the client, but leave the newly created file in place as an artifact.
  The file creation code path has been reorganized so that internal
  failures and race conditions are less likely to result in an unwanted
  file creation.

  A fault injector has been added to help exercise paths that are run
  during kernel metadata cache invalidation. These caches contain
  information maintained by user space about exported filesystems. Many
  of our test workloads do not trigger cache invalidation.

  There is one patch that is needed to support PREEMPT_RT and a fix for
  an ancient 'sleep while spin-locked' splat that seems to have become
  easier to hit since v5.18-rc3"

Pull modules updates from  Luis Chamberlain:

 - It was time to tidy up kernel/module.c and one way of starting with
   that effort was to split it up into files. At my request Aaron Tomlin
   spearheaded that effort with the goal to not introduce any functional
   at all during that endeavour. The penalty for the split is +1322
   bytes total, +112 bytes in data, +1210 bytes in text while bss is
   unchanged. One of the benefits of this other than helping make the
   code easier to read and review is summoning more help on review for
   changes with livepatching so kernel/module/livepatch.c is now pegged
   as maintained by the live patching folks.

   The before and after with just the move on a defconfig on x86-64:

 - Aaron added module unload taint tracking (MODULE_UNLOAD_TAINT_TRACKING),
   to enable tracking unloaded modules which did taint the kernel.

 - Christophe Leroy added CONFIG_ARCH_WANTS_MODULES_DATA_IN_VMALLOC
   which lets architectures to request having modules data in vmalloc
   area instead of module area. There are three reasons why an
   architecture might want this:

    a) On some architectures (like book3s/32) it is not possible to
       protect against execution on a page basis. The exec stuff can be
       mapped by different arch segment sizes (on book3s/32 that is 256M
       segments). By default the module area is in an Exec segment while
       vmalloc area is in a NoExec segment. Using vmalloc lets you muck
       with module data as NoExec on those architectures whereas before
       you could not.

    b) By pushing more module data to vmalloc you also increase the
       probability of module text to remain within a closer distance
       from kernel core text and this reduces trampolines, this has been
       reported on arm first and powerpc folks are following that lead.

    c) Free'ing module_alloc() (Exec by default) area leaves this
       exposed as Exec by default, some architectures have some security
       enhancements to set this as NoExec on free, and splitting module
       data with text let's future generic special allocators be added
       to the kernel without having developers try to grok the tribal
       knowledge per arch. Work like Rick Edgecombe's permission vmalloc
       interface [0] becomes easier to address over time.

     we supported that has no MMU implementation, but there are still a
     few architectures (arm, m68k, riscv, sh and xtensa) that support
     CPUs with and without an MMU.

   - A series to add a generic ticket spinlock that can be shared by
     most architectures with a working cmpxchg or ll/sc type atomic,
     including the conversion of riscv, csky and openrisc. This series
     is also a prerequisite for the loongarch64 architecture port that
     will come as a separate pull request.

   - A cleanup of some exported uapi header files to ensure they can be
     included from user space without relying on other kernel headers"

Pull ARMv4T/v5 multiplatform support from Arnd Bergmann:
 "This series has been 12 years in the making, it mostly finishes the
  work that was started with the founding of Linaro to clean up platform
  support in the kernel.

  The largest change here is a cleanup of the omap1 platform, which is
  the final ARM machine type to get converted to the common-clk
  subsystem. All the omap1 specific drivers are now made independent of
  the mach/*.h headers to allow the platform to be part of a generic
  ARMv4/v5 multiplatform kernel.

  The last bit that enables this support is still missing here while we
  wait for some last dependencies to make it into the mainline kernel
  through other subsystems.

  The s3c24xx, ixp4xx, iop32x, ep93xx and dove platforms were all almost
  at the point of allowing multiplatform kernels, this work gets
  completed here along with a few additional cleanup. At the same time,
  the s3c24xx and s3c64xx are now deprecated and expected to get removed
  in the future.

  The PXA and OMAP1 bits are in a separate branch because of
  dependencies. Once both branches are merged, only the three Intel
  StrongARM platforms (RiscPC, Footbridge/NetWinder and StrongARM1100)
  need separate kernels, and there are no plans to include these"

Pull ARM driver updates from Arnd Bergmann:
 "There are minor updates to SoC specific drivers for chips by Rockchip,
  Samsung, NVIDIA, TI, NXP, i.MX, Qualcomm, and Broadcom.

  Noteworthy driver changes include:

   - Several conversions of DT bindings to yaml format.

   - Renesas adds driver support for R-Car V4H, RZ/V2M and RZ/G2UL SoCs.

   - Qualcomm adds a bus driver for the SSC (Snapdragon Sensor Core),
     and support for more chips in the RPMh power domains and the
     soc-id.

   - NXP has a new driver for the HDMI blk-ctrl on i.MX8MP.

   - Apple M1 gains support for the on-chip NVMe controller, making it
     possible to finally use the internal disks. This also includes SoC
     drivers for their RTKit IPC and for the SART DMA address filter.

  For other subsystems that merge their drivers through the SoC tree, we
  have

   - Firmware drivers for the ARM firmware stack including TEE, OP-TEE,
     SCMI and FF-A get a number of smaller updates and cleanups. OP-TEE
     now has a cache for firmware argument structures as an
     optimization, and SCMI now supports the 3.1 version of the

Now that there are no more callers of nfsd_file_put() that might
hold a spin lock, ensure the lockdep infrastructure can catch
newly introduced calls to nfsd_file_put() made while a spinlock
is held.

Refactor: Use existing helpers that other lock operations use. This

Signed-off-by: Chuck Lever <chuck.lever@oracle.com>

nfsd4_release_lockowner() holds clp->cl_lock when it calls
check_for_locks(). However, check_for_locks() calls nfsd_file_get()
/ nfsd_file_put() to access the backing inode's flc_posix list, and
nfsd_file_put() can sleep if the inode was recently removed.

Let's instead rely on the stateowner's reference count to gate
whether the release is permitted. This should be a reliable
indication of locks-in-use since file lock operations and
->lm_get_owner take appropriate references, which are released
appropriately when file locks are removed.

Pull xfs updates from Dave Chinner:
 "This is a big update with lots of new code. The summary below them
  all, so I'll just touch on teh higlights. The two main new features
  are Large Extent Counts and Logged Attribute Replay - these are two
  new foundational features that we are building more complex future
  features on top of.

  For upcoming functionality, we need to be able to store hundreds of
  millions of xattrs per inode. The Large Extent Count feature removes
  the limits that prevent this scale of xattr storage, and while we were
  modifying the on disk extent count format we also increased the number
  of data extents we support per inode from 2^32 to 2^47.

  We also need to be able to modify xattrs as part of larger atomic
  transactions rather than as standalone transactions. The Logged
  Attribute Replay feature introduces the infrastructure that allows us
  to use intents to record the attribute modifications in the journal
  before we start them, hence allowing other atomic transactions to log
  attribute modification intents and then defer the actual modification
  to later. If we then crash, log recovery then guarantees that the
  attribute is replayed in the context of the atomic transaction that
  logged the intent.

  A significant chunk of the commits in this merge are for the base
  attribute replay functionality along with fixes, improvements and
  cleanups related to this new functioanlity. Allison deserves a big
  round of thanks for her ongoing work to get this functionality into
  XFS.

  There are also many other smaller changes and improvements, so overall
  this is one of the bigger XFS merge requests in some time.

  I will be following up next week with another smaller pull request -
  we already have another round of fixes and improvements to the logged
  attribute replay functionality just about ready to go. They'll soak
  and test over the next week, and I'll send a pull request for them
  near the end of the merge window.

  Summary:

   - support for printk message indexing.

   - large extent counts to provide support for up to 2^47 data extents
     and 2^32 attribute extents, allowing us to scale beyond 4 billion
     data extents to billions of xattrs per inode.

   - conversion of various flags fields to be consistently declared as
     unsigned bit fields.

   - improvements to realtime extent accounting and converts them to
     per-cpu counters to match all the other block and inode accounting.

   - reworks core log formatting code to reduce iterations, have a
     shorter, cleaner fast path and generally be easier to understand
     and maintain.

   - improvements to rmap btree searches that reduce overhead by up to
     30% resulting in xfs_scrub runtime reductions of 15%.

   - improvements to reflink that remove the size limitations in
     remapping operations and greatly reduce the size of transaction
     reservations.

   - reworks the minimum log size calculations to allow us to change
     transaction reservations without changing the minimum supported log
     size.

   - removal of quota warning support as it has never been used on
     Linux.

   - intent whiteouts to allow us to cancel intents that are completed
     entirely in memory rather than having use CPU and disk bandwidth
     formatting and writing them into the journal when it is not
     necessary. This makes rmap, reflink and extent freeing slightly
     more efficient, but provides massive improvements for....

   - Logged Attribute Replay feature support. This is a fundamental
     change to the way we modify attributes, laying the foundation for
     future integration of attribute modifications as part of other
     atomic transactional operations the filesystem performs.

   - Lots of cleanups and fixes for the logged attribute replay
     functionality"

Pull perf tool updates from Arnaldo Carvalho de Melo:
 "Intel PT:

   - Allow hardware tracing on KVM test programs. In this case, the VM
     is not running an OS, but only the functions loaded into it by the
     hypervisor test program, and conveniently, loaded at the same
     virtual addresses.

   - Improve documentation:
      - Add link to perf wiki's page

   - Cleanups:
      - Delete now unused perf-with-kcore.sh script
      - Remove unused machines__find_host()

  ARM SPE (Statistical Profile Extensions):

   - Add man page entry.

  Vendor Events:

   - Update various Intel event topics

   - Update various microarch events

   - Fix various cstate metrics

   - Fix Alderlake metric groups

   - Add sapphirerapids events

   - Add JSON files for ARM Cortex A34, A35, A55, A510, A65, A73, A75,
     A77, A78, A710, X1, X2 and Neoverse E1

   - Update Cortex A57/A72

  perf stat:

   - Introduce stats for the user and system rusage times

  perf c2c:

   - Prep work to support ARM systems

  perf annotate:

   - Add --percent-limit option

  perf lock:

   - Add -t/--thread option for report

   - Do not discard broken lock stats

  perf bench:

   - Fix test case 81 ("perf record tests") on s390x

  perf version:

   - debuginfod support improvements

  perf scripting python:

   - Expose symbol offset and source information

  perf build:

   - Error for BPF skeletons without LIBBPF

   - Use Python devtools for version autodetection rather than runtime

  Miscellaneous:

   - Add riscv64 support to 'perf jitdump'

   - Various fixes/tidy ups related to cpu_map

   - Fixes for handling Intel hybrid systems"
