      Merge tag 'irqchip-fixes-5.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/urgent

Pull irqchip fixes from Marc Zyngier:

  - Address an issue with the SiFive PLIC being unable to EOI
    a masked interrupt

  - Move the disable/enable methods in the CSky mpintc to
    mask/unmask

  - Fix a regression in the OF irq code where an interrupt-controller
    property in the same node as an interrupt-map property would get
    ignored

      Pull zstd update from Nick Terrell:
 "Update to zstd-1.4.10.

  Add myself as the maintainer of zstd and update the zstd version in
  the kernel, which is now 4 years out of date, to a much more recent
  zstd release. This includes bug fixes, much more extensive fuzzing,
  and performance improvements. And generates the kernel zstd
  automatically from upstream zstd, so it is easier to keep the zstd
  verison up to date, and we don't fall so far out of date again.

  This includes 5 commits that update the zstd library version:

   - Adds a new kernel-style wrapper around zstd.

     This wrapper API is functionally equivalent to the subset of the
     current zstd API that is currently used. The wrapper API changes to
     be kernel style so that the symbols don't collide with zstd's
     symbols. The update to zstd-1.4.10 maintains the same API and
     preserves the semantics, so that none of the callers need to be
     updated. All ca...

      Pull virtio-mem update from David Hildenbrand:
 "Support the VIRTIO_MEM_F_UNPLUGGED_INACCESSIBLE feature in virtio-mem,
  now that "accidential" access to logically unplugged memory inside
  added Linux memory blocks is no longer possible, because we:

   - Removed /dev/kmem in commit bbcd53c9 ("drivers/char: remove
     /dev/kmem for good")

   - Disallowed access to virtio-mem device memory via /dev/mem in
     commit 2128f4e2 ("virtio-mem: disallow mapping virtio-mem memory
     via /dev/mem")

   - Sanitized access to virtio-mem device memory via /proc/kcore in
     commit 0daa322b ("fs/proc/kcore: don't read offline sections,
     logically offline pages and hwpoisoned pages")

   - Sanitized access to virtio-mem device memory via /proc/vmcore in
     commit ce281462 ("virtio-mem: kdump mode to sanitize
     /proc/vmcore access")

  The new VIRTIO_MEM_F_UNPLUGGED_INACCESSIBLE feature that will be

      perf tests: Remove bash constructs from stat_all_pmu.sh · ac96f463

The tests were passing but without testing and were printing the
following:

  $ ./perf test -v 90
  90: perf all PMU test                                               :
  --- start ---
  test child forked, pid 51650
  Testing cpu/branch-instructions/
  ./tests/shell/stat_all_pmu.sh: 10: [:
   Performance counter stats for 'true':

             137,307      cpu/branch-instructions/

         0.001686672 seconds time elapsed

         0.001376000 seconds user
         0.000000000 seconds sys: unexpected operator

Changing the regexes to a grep works in sh and prints this:

  $ ./perf test -v 90
  90: perf all PMU test                                               :

  test child finished with 0
