3fe2f7446f Changes in this cycle were:
- Cleanups for SCHED_DEADLINE
  - Tracing updates/fixes
  - CPU Accounting fixes
  - First wave of changes to optimize the overhead of the scheduler build,
    from the fast-headers tree - including placeholder *_api.h headers for
    later header split-ups.
  - Preempt-dynamic using static_branch() for ARM64
  - Isolation housekeeping mask rework; preperatory for further changes
  - NUMA-balancing: deal with CPU-less nodes
  - NUMA-balancing: tune systems that have multiple LLC cache domains per node (eg. AMD)
  - Updates to RSEQ UAPI in preparation for glibc usage
  - Lots of RSEQ/selftests, for same
  - Add Suren as PSI co-maintainer

515dcdcd48 NFS: nfsiod should not block forever in mempool_alloc()
The concern is that since nfsiod is sometimes required to kick off a
commit, it can get locked up waiting forever in mempool_alloc() instead
of failing gracefully and leaving the commit until later.

Try to allocate from the slab first, with GFP_KERNEL | __GFP_NORETRY,
then fall back to a non-blocking attempt to allocate from the memory
pool.

33e5c765bc NFS: Fix memory allocation in rpc_malloc()
When in a low memory situation, we do want rpciod to kick off direct
reclaim in the case where that helps, however we don't want it looping
forever in mempool_alloc().
So first try allocating from the slab using GFP_KERNEL | __GFP_NORETRY,
and then fall back to a GFP_NOWAIT allocation from the mempool.

Ditto for rpc_alloc_task()

Avoid socket state races due to repeated calls to ->connect() using the

Pull btrfs updates from David Sterba:
 "This contains feature updates, performance improvements, preparatory
  and core work and some related VFS updates:

  Features:

   - encoded read/write ioctls, allows user space to read or write raw
     data directly to extents (now compressed, encrypted in the future),
     will be used by send/receive v2 where it saves processing time

   - zoned mode now works with metadata DUP (the mkfs.btrfs default)

   - error message header updates:
      - print error state: transaction abort, other error, log tree
        errors
      - print transient filesystem state: remount, device replace,
        ignored checksum verifications

   - tree-checker: verify the transaction id of the to-be-written dirty
     extent buffer

  Performance improvements for fsync:

   - directory logging speedups (up to -90% run time)

   - avoid logging all directory changes during renames (up to -60% run
     time)

   - avoid inode logging during rename and link when possible (up to
     -60% run time)

   - prepare extents to be logged before locking a log tree path
     (throughput +7%)

   - stop copying old file extents when doing a full fsync()

   - improved logging of old extents after truncate

  Core, fixes:

   - improved stale device identification by dev_t and not just path
     (for devices that are behind other layers like device mapper)

   - continued extent tree v2 preparatory work
      - disable features that won't work yet
      - add wrappers and abstractions for new tree roots

   - improved error handling

   - add super block write annotations around background block group
     reclaim

   - fix device scanning messages potentially accessing stale pointer

   - cleanups and refactoring

  VFS:

   - allow reflinks/deduplication from two different mounts of the same
     filesystem

   - export and add helpers for read/write range verification, for the
     encoded ioctls"

881b568756 fscrypt updates for 5.18
Add support for direct I/O on encrypted files when blk-crypto (inline
 encryption) is being used for file contents encryption.
 
 There will be a merge conflict with the block pull request in
 fs/iomap/direct-io.c, due to some bio interface cleanups.  The merge
 resolution is straightforward and can be found in linux-next.

0313bc278d Revert "random: block in /dev/urandom"
This reverts commit 6f98a4bfee.

It turns out we still can't do this.  Way too many platforms that don't
have any real source of randomness at boot and no jitter entropy because
they don't even have a cycle counter.

As reported by Guenter Roeck:

 "This causes a large number of qemu boot test failures for various
  architectures (arm, m68k, microblaze, sparc32, xtensa are the ones I
  observed).

  Common denominator is that boot hangs at 'Saving random seed:'"

This isn't hugely unexpected - we tried it, it failed, so now we'll
revert it.

Pull selinux updates from Paul Moore:
 "We've got a number of SELinux patches queued up, the highlights are:

   - Fixup the security_fs_context_parse_param() LSM hook so it executes
     all of the LSM hook implementations unless a serious error occurs.

     We also correct the SELinux hook implementation so that it returns
     zero on success.

   - In addition to a few SELinux mount option parsing fixes, we
     simplified the parsing by moving it earlier in the process.

     The logic was that it was unlikely an admin/user would use the new
     mount API and not have the policy loaded before passing the SELinux
     options.

   - Properly fixed the LSM/SELinux/SCTP hooks with the addition of the
     security_sctp_assoc_established() hook.

     This work was done in conjunction with the netdev folks and should
     complete the move of the SCTP labeling from the endpoints to the
     associations.

   - Fixed a variety of sparse warnings caused by changes in the "__rcu"
     markings of some core kernel structures.

   - Ensure we access the superblock's LSM security blob using the
     stacking-safe accessors.

   - Added the ability for the kernel to always allow FIOCLEX and
     FIONCLEX if the "ioctl_skip_cloexec" policy capability is
     specified.

   - Various constifications improvements, type casting improvements,
     additional return value checks, and dead code/parameter removal.

   - Documentation fixes"

863a66cdb4 lib/sbitmap: allocate sb->map via kvzalloc_node
sbitmap has been used in scsi for replacing atomic operations on
sdev->device_busy, so IOPS on some fast scsi storage can be improved.

However, sdev->device_busy can be changed in fast path, so we have to
allocate the sb->map statically. sdev->device_busy has been capped to 1024,
but some drivers may configure the default depth as < 8, then
cause each sbitmap word to hold only one bit. Finally 1024 * 128(
sizeof(sbitmap_word)) bytes is needed for sb->map, given it is order 5
allocation, sometimes it may fail.

Avoid the issue by using kvzalloc_node() for allocating sb->map.

ad9c6ee642 spi: Updates for v5.18
The overwhelming bulk of this pull request is a change from Uwe
 Kleine-König which changes the return type of the remove() function to
 void as part of some wider work he's doing to do this for all bus types,
 causing updates to most SPI device drivers.  The branch with that on has
 been cross merged with a couple of other trees which added new SPI
 drivers this cycle, I'm not expecting any build issues resulting from
 the change.
 
 Otherwise it's been a relatively quiet release with some new device
 support, a few minor features and the welcome completion of the
 conversion of the subsystem to use GPIO descriptors rather than numbers:
 
  - Change return type of remove() to void.
  - Completion of the conversion of SPI controller drivers to use GPIO
    descriptors rather than numbers.
  - Quite a few DT schema conversions.
  - Support for multiple SPI devices on a bus in ACPI systems.
  - Big overhaul of the PXA2xx SPI driver.
  - Support for AMD AMDI0062, Intel Raptor Lake, Mediatek MT7986 and
    MT8186, nVidia Tegra210 and Tegra234, Renesas RZ/V2L, Tesla FSD and
    Sunplus SP7021.

RISC-V: Add sscofpmf extension support
The sscofpmf extension allows counter overflow and filtering for
programmable counters. Enable the perf driver to handle the overflow
interrupt. The overflow interrupt is a hart local interrupt.
Thus, per cpu overflow interrupts are setup as a child under the root
INTC irq domain.

privilege mode which will be added in future.

It also allows to monitor a handful of firmware counters that can provide

RISC-V: Add a simple platform driver for RISC-V legacy perf
The old RISC-V perf implementation allowed counting of only

However, it provides an easy way out in future where we can remove the

Pull random number generator updates from Jason Donenfeld:
 "There have been a few important changes to the RNG's crypto, but the
  intent for 5.18 has been to shore up the existing design as much as
  possible with modern cryptographic functions and proven constructions,
  rather than actually changing up anything fundamental to the RNG's
  design.

  So it's still the same old RNG at its core as before: it still counts
  entropy bits, and collects from the various sources with the same
  heuristics as before, and so forth. However, the cryptographic
  algorithms that transform that entropic data into safe random numbers
  have been modernized.

  Just as important, if not more, is that the code has been cleaned up
  and re-documented. As one of the first drivers in Linux, going back to
  1.3.30, its general style and organization was showing its age and
  becoming both a maintenance burden and an auditability impediment.

  Hopefully this provides a more solid foundation to build on for the
  future. I encourage you to open up the file in full, and maybe you'll
  remark, "oh, that's what it's doing," and enjoy reading it. That, at
  least, is the eventual goal, which this pull begins working toward.

  Here's a summary of the various patches in this pull:

   - /dev/urandom and /dev/random now do the same thing, per the patch
     we discussed on the list. I think this is worth trying out. If it
     does appear problematic, I've made sure to keep it standalone and
     revertible without any conflicts.

   - Fixes and cleanups for numerous integer type problems, locking
     issues, and general code quality concerns.

   - The input pool's LFSR has been replaced with a cryptographically
     secure hash function, which has security and performance benefits
     alike, and consequently allows us to count entropy bits linearly.

   - The pre-init injection now uses a real hash function too, instead
     of an LFSR or vanilla xor.

   - The interrupt handler's fast_mix() function now uses one round of
     SipHash, rather than the fake crypto that was there before.

   - All additions of RDRAND and RDSEED now go through the input pool's
     hash function, in part to mitigate ridiculous hypothetical CPU
     backdoors, but more so to have a consistent interface for ingesting
     entropy that's easy to analyze, making everything happen one way,
     instead of a potpourri of different ways.

   - The crng now works on per-cpu data, while also being in accordance
     with the actual "fast key erasure RNG" design. This allows us to
     fix several boot-time race complications associated with the prior
     dynamically allocated model, eliminates much locking, and makes our
     backtrack protection more robust.

   - Batched entropy now erases doled out values so that it's backtrack
     resistant.

   - Working closely with Sebastian, the interrupt handler no longer
     needs to take any locks at all, as we punt the
     synchronized/expensive operations to a workqueue. This is
     especially nice for PREEMPT_RT, where taking spinlocks in irq
     context is problematic. It also makes the handler faster for the
     rest of us.

   - Also working with Sebastian, we now do the right thing on CPU
     hotplug, so that we don't use stale entropy or fail to accumulate
     new entropy when CPUs come back online.

   - We handle virtual machines that fork / clone / snapshot, using the
     "vmgenid" ACPI specification for retrieving a unique new RNG seed,
     which we can use to also make WireGuard (and in the future, other
     things) safe across VM forks.

   - Around boot time, we now try to reseed more often if enough entropy
     is available, before settling on the usual 5 minute schedule.

   - Last, but certainly not least, the documentation in the file has
     been updated considerably"

Pull ACPI updates from Rafael Wysocki:
 "From the new functionality perspective, the most significant items
  here are the new driver for the 'ARM Generic Diagnostic Dump and
  Reset' device, the extension of fine grain fan control in the ACPI fan
  driver, and the change making it possible to use CPPC information to
  obtain CPU capacity.

  There are also a few new quirks, a bunch of fixes, including the
  platform-level _OSC handling change to make it actually take the
  platform firmware response into account, some code and documentation
  cleanups, and a notable update of the ACPI device enumeration
  documentation.

  Specifics:

   - Use uintptr_t and offsetof() in the ACPICA code to avoid compiler
     warnings regarding NULL pointer arithmetic (Rafael Wysocki).

   - Fix possible NULL pointer dereference in acpi_ns_walk_namespace()
     when passed "acpi=off" in the command line (Rafael Wysocki).

bba90e0964 Core code updates:
- Reduce the amount of work to release a task stack in context
     switch. There is no real reason to do cgroup accounting and memory
     freeing in this performance sensitive context. Aside of this the
     invoked functions cannot be called from this preemption disabled
     context on PREEMPT_RT enabled kernels. Solve this by moving the
     accounting into do_exit() and delaying the freeing of the stack unless
     the vmap stack can be cached.
 
   - Provide a mechanism to delay raising signals from atomic context on
     PREEMPT_RT enabled kernels as sighand::lock cannot be acquired.  Store
     the information in the task struct and raise it in the exit path.

Pull core process handling RT latency updates from Thomas Gleixner:

 - Reduce the amount of work to release a task stack in context switch.
   There is no real reason to do cgroup accounting and memory freeing in
   this performance sensitive context.

   Aside of this the invoked functions cannot be called from this
   preemption disabled context on PREEMPT_RT enabled kernels. Solve this
   by moving the accounting into do_exit() and delaying the freeing of
   the stack unless the vmap stack can be cached.

 - Provide a mechanism to delay raising signals from atomic context on
   PREEMPT_RT enabled kernels as sighand::lock cannot be acquired. Store
   the information in the task struct and raise it in the exit path.

3fd33273a4 Reenable ENQCMD/PASID support:
- Simplify the PASID handling to allocate the PASID once, associate it to
    the mm of a process and free it on mm_exit(). The previous attempt of
    refcounted PASIDs and dynamic alloc()/free() turned out to be error
    prone and too complex. The PASID space is 20bits, so the case of
    resource exhaustion is a pure academic concern.
 
  - Populate the PASID MSR on demand via #GP to avoid racy updates via IPIs.
 
  - Reenable ENQCMD and let objtool check for the forbidden usage of ENQCMD
    in the kernel.
 
  - Update the documentation for Shared Virtual Addressing accordingly.

351bdbb641 net: Revert the softirq will run annotation in ____napi_schedule().
The lockdep annotation lockdep_assert_softirq_will_run() expects that
either hard or soft interrupts are disabled because both guaranty that
the "raised" soft-interrupts will be processed once the context is left.

This triggers in flush_smp_call_function_from_idle() but it this case it
explicitly calls do_softirq() in case of pending softirqs.

Revert the "softirq will run" annotation in ____napi_schedule() and move
the check back to __netif_rx() as it was. Keep the IRQ-off assert in
____napi_schedule() because this is always required.

Fixes: fbd9a2ceba ("net: Add lockdep asserts to ____napi_schedule().")
