Pull iommufd updates from Jason Gunthorpe:

 - The iova_bitmap logic for efficiently reporting dirty pages back to
   userspace has a few more tricky corner case bugs that have been
   resolved and backed with new tests.

   The revised version has simpler logic.

 - Shared branch with iommu for handle support when doing domain attach.

   Handles allow the domain owner to include additional private data on
   a per-device basis.

 - IO Page Fault Reporting to userspace via iommufd. Page faults can be
   generated on fault capable HWPTs when a translation is not present.

   Routing them to userspace would allow a VMM to be able to virtualize
   them into an emulated vIOMMU. This is the next step to fully enabling

This commit introduces a new 'I' mode for dm-integrity.

The 'I' mode may be selected if the underlying device has non-power-of-2
sector size. In this mode, dm-integrity will store integrity data
directly in device's sectors and it will not use journal.

This mode improves performance and reduces flash wear because there would
be no journal writes.

Pull bcachefs updates from Kent Overstreet:

 - Metadata version 1.8: Stripe sectors accounting, BCH_DATA_unstriped

   This splits out the accounting of dirty sectors and stripe sectors in
   alloc keys; this lets us see stripe buckets that still have unstriped
   data in them.

   This is needed for ensuring that erasure coding is working correctly,
   as well as completing stripe creation after a crash.

 - Metadata version 1.9: Disk accounting rewrite

   The previous disk accounting scheme relied heavily on percpu counters
   that were also sharded by outstanding journal buffer; it was fast but
   not extensible or scalable, and meant that all accounting counters
   were recorded in every journal entry.

   The new disk accounting scheme stores accounting as normal btree
   keys; updates are deltas until they are flushed by the btree write
   buffer.

   This means we have no practical limit on the number of counters, and
   a new tagged union format that's easy to extend.

   We now have counters for compression type/ratio, per-snapshot-id
   usage, per-btree-id usage, and pending rebalance work.

 - Self healing on read IO/checksum error

   Data is now automatically rewritten if we get a read error and then a
   successful retry

 - Mount API conversion (thanks to Thomas Bertschinger)

 - Better lockdep coverage

   Previously, btree node locks were tracked individually by lockdep,
   like any other lock. But we may take _many_ btree node locks
   simultaneously, we easily blow through the limit of 48 locks that
   lockdep can track, leading to lockdep turning itself off.

   Tracking each btree node lock individually isn't really necessary
   since we have our own cycle detector for deadlock avoidance and
   centralized tracking of btree node locks, so we now have a single
   lockdep_map in btree_trans for "any btree nodes are locked".

 - Some more small incremental work towards online check_allocations

 - Lots more debugging improvements

 - Fixes, including:
    - undefined behaviour fixes, originally noted as breaking userspace
      LTO builds
    - fix a spurious warning in fsck_err, reported by Marcin
    - fix an integer overflow on trans->nr_updates, also reported by
      Marcin; this broke during deletion of highly fragmented indirect

  around, mostly more of the usual:

   - More Spanish, Italian, and Chinese translations

   - A new script, scripts/checktransupdate.py, can be used to see which
     commits have touched an (English) document since a given
     translation was last updated.

   - A couple of "best practices" suggestions (on Link: tags and
     off-list discussions) that were not entirely at consensus level,
     but I concluded they were close enough to accept.

   - Some nice cleanups removing documentation for kernel parameters
     that have not been recognized for ... a long time.

  ...along with the usual updates, typo fixes, and such"

If a btree_trans is in use it's supposed to be passed to fsck_err so
that it can be unlocked if we're waiting on userspace input; but the
btree IO paths do call fsck errors where a btree_trans exists on the
stack but it's not passed through.

But it's ok, because it's unlocked while doing IO.

 "The most prominent change this time is the kmem_buckets based
  hardening of kmalloc() allocations from Kees Cook.

  We have also extended the kmalloc() alignment guarantees for
  non-power-of-two sizes in a way that benefits rust.

  The rest are various cleanups and non-critical fixups.

   - Dedicated bucket allocator (Kees Cook)

     This series [1] enhances the probabilistic defense against heap
     spraying/grooming of CONFIG_RANDOM_KMALLOC_CACHES from last year.

     kmalloc() users that are known to be useful for exploits can get
     completely separate set of kmalloc caches that can't be shared with
     other users. The first converted users are alloc_msg() and
     memdup_user().

     The hardening is enabled by CONFIG_SLAB_BUCKETS.

   - Extended kmalloc() alignment guarantees (Vlastimil Babka)

     For years now we have guaranteed natural alignment for power-of-two
     allocations, but nothing was defined for other sizes (in practice,
     we have two such buckets, kmalloc-96 and kmalloc-192).

     To avoid unnecessary padding in the rust layer due to its alignment
     rules, extend the guarantee so that the alignment is at least the
     largest power-of-two divisor of the requested size.

     This fits what rust needs, is a superset of the existing
     power-of-two guarantee, and does not in practice change the layout
     (and thus does not add overhead due to padding) of the kmalloc-96
     and kmalloc-192 caches, unless slab debugging is enabled for them.

   - Cleanups and non-critical fixups (Chengming Zhou, Suren
     Baghdasaryan, Matthew Willcox, Alex Shi, and Vlastimil Babka)

     Various tweaks related to the new alloc profiling code, folio
     conversion, debugging and more leftovers after SLAB"

   - Fix -r/--repeat option of perf sched replay

     The documentation said -1 will work as infinity but it didn't
     accept the value. Update the code and document to use 0 instead

   - Fix perf sched timehist to account the delay time for preempted
     tasks

  Perf event filtering:

   - perf top gained filtering support on regular events using BPF like
     perf record. Previously it was able to use it for tracepoints only

   - The BPF filter now supports filtering by UID/GID. This should be
     preferred than -u <UID> option as it's racy to scan /proc to check
     tasks for the user and fails to open an event for the task if it's
     already gone

       $ sudo perf top -e cycles --filter "uid == $(id -u)"

  perf report:

   - Skip dummy events in the group output by default. The --skip-empty
     option controls display of empty events without samples. But perf
     report can force display all events in a group

     In this case, auto-added a dummy event (for a system-wide record)
     ends up in the output. Now it can skip those empty events even in
     the group display mode

     To preserve the old behavior, run this:

       $ perf report --group --no-skip-empty

  perf stat:

   - Choose the most disaggregate option when multiple aggregation
     options are given. It used to pick the last option in the command
     line but it can be confusing and not consistent. Now it'll choose
     the smallest unit

     For example, it'd aggregate the result per-core when the user gave
     both --per-socket and --per-core options at the same time

  Internals:

   - Fix `perf bench` when some CPUs are offline

   - Fix handling of JIT symbol mappings to accept "/tmp/perf-${PID}.map
     patterns only so that it can not be confused by other /tmp/perf-*
     files

   - Many improvements and fixes for `perf test`

 "Rewrite of function graph tracer to allow multiple users

  Up until now, the function graph tracer could only have a single user
  attached to it. If another user tried to attach to the function graph
  tracer while one was already attached, it would fail. Allowing
  function graph tracer to have more than one user has been asked for
  since 2009, but it required a rewrite to the logic to pull it off so
  it never happened. Until now!

  There's three systems that trace the return of a function. That is
  kretprobes, function graph tracer, and BPF. kretprobes and function
  graph tracing both do it similarly. The difference is that kretprobes
  uses a shadow stack per callback and function graph tracer creates a
  shadow stack for all tasks. The function graph tracer method makes it
  possible to trace the return of all functions. As kretprobes now needs
  that feature too, allowing it to use function graph tracer was needed.
  BPF also wants to trace the return of many probes and its method
  doesn't scale either. Having it use function graph tracer would
  improve that.

  By allowing function graph tracer to have multiple users allows both
  kretprobes and BPF to use function graph tracer in these cases. This
  will allow kretprobes code to be removed in the future as it's version
  will no longer be needed.

  Note, function graph tracer is only limited to 16 simultaneous users,
  due to shadow stack size and allocated slots"

Commit 50b040ef ("PCI/pwrctl: only call of_platform_populate() if
CONFIG_OF is enabled") added the CONFIG_OF guard for the
of_platform_populate() API.  But it missed the fact that the CONFIG_OF
platforms can also run on ACPI without devicetree (so dev.of_node will
be NULL).  In those cases, of_platform_populate() will fail with below
error messages as seen on the Ampere Altra box:

  pci 000c:00:01.0: failed to populate child OF nodes (-22)
  pci 000c:00:02.0: failed to populate child OF nodes (-22)

Fix this by checking for the existence of 'dev.of_node' before calling
the of_platform_populate() API.  This also warrants the removal of
CONFIG_OF check, since dev_of_node() helper will return NULL if
CONFIG_OF is not enabled.

While at it, let's also use dev_of_node() to pass device OF node pointer
to of_platform_populate().
