 "The most significant item here is the Platform Firmware Runtime Update
  and Telemetry (PFRUT) support designed to allow certain pieces of the
  platform firmware to be updated on the fly, among other things.

  Also important is the e820 handling change on x86 that should work
  around PCI BAR allocation issues on some systems shipping since 2019.

  The rest is just a handful of assorted fixes and cleanups on top of
  the ACPI material merged previously.

  Specifics:

   - Add support for the the Platform Firmware Runtime Update and
     Telemetry (PFRUT) interface based on ACPI to allow certain pieces
     of the platform firmware to be updated without restarting the
     system and to provide a mechanism for collecting platform firmware
     telemetry data (Chen Yu, Dan Carpenter, Yang Yingliang).

   - Ignore E820 reservations covering PCI host bridge windows on
     sufficiently recent x86 systems to avoid issues with allocating PCI
     BARs on systems where the E820 reservations cover the entire PCI
     host bridge memory window returned by the _CRS object in the
     system's ACPI tables (Hans de Goede).

   - Fix and clean up acpi_scan_init() (Rafael Wysocki).

   - Add more sanity checking to ACPI SPCR tables parsing (Mark
     Langsdorf).

   - Fix up ACPI APD (AMD Soc) driver initialization (Jiasheng Jiang).

   - Drop unnecessary "static" from the ACPI PCC address space handling
     driver added recently (kernel test robot)"

     the old /sys/devices/system/cpu/cpuN/topology/core_cpus.

   - Disable debuginfod by default in 'perf record', to avoid stalls on
     distros such as Fedora 35.

   - Use unbuffered output in 'perf bench' when pipe/tee'ing to a file.

     names take into account the architecture where the perf.data file
     was collected.

   - Fix SMT fallback with large core counts.

   - Don't lower case MetricExpr when parsing JSON files so as not to
     lose info such as the ":G" event modifier in metrics.

  perf test:

   - Add basic stress test for sigtrap handling to 'perf test'.

   - Fix 'perf test' failures on s/390

   - Enable system wide for metricgroups test in 'perf test´.

   - Use 3 digits for test numbering now we can have more tests.

  Arch specific:

   - Add events for Arm Neoverse N2 in the ARM JSON vendor event files

   - Support PERF_MEM_LVLNUM encodings in powerpc, that came from a
     single patch series, where I incorrectly merged the kernel bits,
     that were then reverted after coordination with Michael Ellerman
     and Stephen Rothwell.

   - Add ARM SPE total latency as PERF_SAMPLE_WEIGHT.

   - Update AMD documentation, with info on raw event encoding.

   - Add support for global and local variants of the "p_stage_cyc" sort
     key, applicable to perf.data files collected on powerpc.

   - Remove duplicate and incorrect aux size checks in the ARM CoreSight
     ETM code.

  Refactorings:

   - Add a perf_cpu abstraction to disambiguate CPUs and CPU map
     indexes, fixing problems along the way.

   - Document CPU map methods.

  UAPI sync:

   - Update arch/x86/lib/mem{cpy,set}_64.S copies used in 'perf bench
     mem memcpy'

Prior to Linux v5.4 devtmpfs used mount_single() which treats the given
mount options as "remount" options, so it updates the configuration of
the single super_block on each mount.

Since that was changed, the mount options used for devtmpfs are ignored.
This is a regression which affect systemd - which mounts devtmpfs with
"-o mode=755,size=4m,nr_inodes=1m".

This patch restores the "remount" effect by calling reconfigure_single()

  kmod decompression is still done by userspace even with this is done,
  both because there are no measurable gains in not doing so and as it
  adds a secondary extra check for validating the module before loading
  it into the kernel.

  The rest of the changes are minor, the only other change worth
  mentionin there is Jessica Yu is now bowing out of maintenance of

  userspace configured signal delivery state, and for the ptrace stops
  to always happen in locations where we can guarantee on all
  architectures that the all of the registers are saved and available on
  the stack.

  Removal of profile_task_ext, profile_munmap, and profile_handoff_task
  are the big successes for dead code removal this round.

  A bunch of small bug fixes are included, as most of the issues
  reported were small enough that they would not affect bisection so I
  simply added the fixes and did not fold the fixes into the changes
  they were fixing.

  There was a bug that broke coredumps piped to systemd-coredump. I
  dropped the change that caused that bug and replaced it entirely with
  something much more restrained. Unfortunately that required some
  rebasing.

  Some successes after this set of changes: There are few enough calls
  to do_exit to audit in a reasonable amount of time. The lifetime of
  struct kthread now matches the lifetime of struct task, and the
  pointer to struct kthread is no longer stored in set_child_tid. The
  flag SIGNAL_GROUP_COREDUMP is removed. The field group_exit_task is
  removed. Issues where task->exit_code was examined with
  signal->group_exit_code should been examined were fixed.

  There are several loosely related changes included because I am
  cleaning up and if I don't include them they will probably get lost.

  The original postings of these changes can be found at:
     https://lkml.kernel.org/r/87a6ha4zsd.fsf@email.froward.int.ebiederm.org

  I trimmed back the last set of changes to only the obviously correct
  once. Simply because there was less time for review than I had hoped"

Pull tracing updates from Steven Rostedt:
 "New:

   - The Real Time Linux Analysis (RTLA) tool is added to the tools
     directory.

   - Can safely filter on user space pointers with: field.ustring ~
     "match-string"

   - eprobes can now be filtered like any other event.

   - trace_marker(_raw) now uses stream_open() to allow multiple threads
     to safely write to it. Note, this could possibly break existing
     user space, but we will not know until we hear about it, and then
     can revert the change if need be.

   - New field in events to display when bottom halfs are disabled.

   - Sorting of the ftrace functions are now done at compile time
     instead of at bootup.

  Infrastructure changes to support future efforts:

   - Added __rel_loc type for trace events. Similar to __data_loc but
     the offset to the dynamic data is based off of the location of the
     descriptor and not the beginning of the event. Needed for user
     defined events.

   - Some simplification of event trigger code.

   - Make synthetic events process its callback better to not hinder
     other event callbacks that are registered. Needed for user defined
     events.

  And other small fixes and cleanups"

   - fix possible uninitialized memory usage for setattr

   - fix fscache reading hole in a file just after it's been grown

   - split net/9p/trans_fd.c in its own module like other transports.

     The new transport module defaults to 9P_NET and is autoloaded if
     required so users should not be impacted

   - add Christian Schoenebeck to 9p reviewers

   - some more trivial cleanup"

Fedora 35 sets DEBUGINFOD_URLS by default, which might lead to
unexpected stalls in perf record exit path, when we try to cache
profiled binaries.

  # DEBUGINFOD_PROGRESS=1 ./perf record -a
  ^C[ perf record: Woken up 1 times to write data ]
  Downloading from https://debuginfod.fedoraproject.org/ 447069
  Downloading from https://debuginfod.fedoraproject.org/ 1502175
  Downloading \^Z

Disabling DEBUGINFOD_URLS by default in perf record and adding
debuginfod option and .perfconfig variable support to enable id.

  Default without debuginfo processing:
  # perf record -a

  Using system debuginfod setup:
  # perf record -a --debuginfod

  Using custom debuginfd url:
  # perf record -a --debuginfod='https://evenbetterdebuginfodserver.krava

'

Adding single perf_debuginfod_setup function and using
it also in perf buildid-cache command.

The cpumap is dummy, so no need to go on figuring out affinity.o

This way we reduce the setup time for simple scenarios like:

	$ perf stat sleep 1

Needed to check if a cpu_map is dummy, i.e. not a cpu map at all, for
pid monitoring scenarios.

This probably needs to move to libperf, but since perf itself is the
first and so far only user, leave it at tools/perf/util/.

Prepare input updates for 5.17 merge window.

Multiple events may have a metric_leader to aggregate into.

This happens for uncore events where, for example, uncore_imc is
expanded into uncore_imc_0, uncore_imc_1, etc.

Such events all have the same metric_id and should aggregate into the
first event.

The change introducing metric_ids had a bug where the metric_id was
compared to itself, creating an always true condition.

Correct this by comparing the event in the metric_evlist and the
metric_leader.

Fixes: ec5c5b3d
