Picking the changes from:

  81be1093 ("ALSA: pcm: Add SNDRV_PCM_INFO_EXPLICIT_SYNC flag")

Which entails no changes in the tooling side as it doesn't introduce new
ioctls.

  f0376edb ("KVM: arm64: Add ioctl to fetch/store tags in a guest")
  ea7fc1bb ("KVM: arm64: Introduce MTE VM feature")

That just rebuilds perf, as these patches don't add any new KVM ioctl to
be harvested for the the 'perf trace' ioctl syscall argument
beautifiers.

This is also by now used by tools/testing/selftests/kvm/, so that will
pick the new KVM_STATS_TYPE_LINEAR_HIST and KVM_STATS_TYPE_LOG_HIST
defines.

Perf records IBS (Instruction Based Sampling) extra sample data when
'perf record --raw-samples' is used with an IBS-compatible event, on a
machine that supports IBS.  IBS support is indicated in
CPUID_Fn80000001_ECX bit #10.

Up until now, users have been able to see the extra sample data solely
in raw hex format using 'perf report --dump-raw-trace'.  From there,
users could decode the data either manually, or by using an external
script.

Enable the built-in 'perf report --dump-raw-trace' to do the decoding of
the extra sample data bits, so manual or external script decoding isn't
necessary.

Example usage:

  $ sudo perf record -c 10000001 -a --raw-samples -e ibs_fetch/rand_en=1/,ibs_op/cnt_ctl=1/ -C 0,1 taskset -c 0,1 7za b -mmt2 | perf report --dump-raw-trace

Stdout contains IBS Fetch samples, e.g.:

  ibs_fetch_ctl:	02170007ffffffff MaxCnt 1048560 Cnt 1048560 Lat     7 En 1 Val 1 Comp 1 IcMiss 0 PhyAddrValid 1 L1TlbPgSz 4KB L1TlbMiss 0 L2TlbMiss 0 RandEn 1 L2Miss 0

  cc1: all warnings being treated as errors

As that %2d won't limit the number of chars to 2, just state that 2 is
the minimal width:

  $ cat printf.c
  #include <stdio.h>
  #include <stdlib.h>

  int main(int argc, char *argv[])
  {
  	char bf[64];
  	int len = snprintf(bf, sizeof(bf), "%2d", atoi(argv[1]));

  	printf("strlen(%s): %u\n", bf, len);

  	return 0;
  }
  $ ./printf 1
  strlen( 1): 2
  $ ./printf 12
  strlen(12): 2
  $ ./printf 123
  strlen(123): 3
  $ ./printf 1234
  strlen(1234): 4
  $ ./printf 12345
  strlen(12345): 5
  $ ./printf 123456
  strlen(123456): 6
  $

And since we probably don't want that output to be truncated, just
assume the worst case, as the compiler did, and add a few more chars to
that buffer.

Also use sizeof(var) instead of sizeof(dup-of-wanted-format-string) to
avoid bugs when changing one but not the other.

I also had to change this:

  -#include <asm/amd-ibs.h>
  +#include "../../arch/x86/include/asm/amd-ibs.h"

To make it build on other architectures, just like intel-pt does.

This is a tools/-side patch for the patch that adds the original copy
of the IBS header file, in arch/x86/include/asm/.

We also add an entry to check-headers.sh, so future changes continue
to be copied.

Committer notes:

Had to add this

  -#include <asm/msr-index.h>
  +#include "msr-index.h"

And change the check-headers.sh entry to ignore this line when diffing
with the original kernel header.

This is needed so that we can use 'perf report' on a perf.data with IBS
data on a !x86 system, i.e. building on ARM fails without this as there
is no asm/msr-index.h there.

This was done on the next patch in this series and is done for things
like Intel PT and ARM CoreSight.

To be used by IBS raw data display: It needs the recorder's cpuid in
order to determine which errata workarounds to apply to the data, and
the pmu_mappings are needed in order to figure out which PMU sample
type is IBS Fetch vs. IBS Op.

When not available from perf.data, we assume local operation, and
retrieve cpuid and pmu mappings directly from the running system.

Instead of using the file offset in the debug file.

This fixes a regression from 00a34234 ("perf symbols: Make
dso__load_bfd_symbols() load PE files from debug cache only"), causing
incorrect symbol resolution when debug file have been stripped from
non-debug sections (in which case its .text section is empty and doesn't
have any file position).

The debug files could also be created with a different file alignment,
and have different file positions from the mmap-ed binary, or have the
section reordered.

This instead looks for the file image base, using the corresponding bfd
*ABS* symbols. As PE symbols only have 4 bytes, it also needs to keep
.text section vma high bits.

tools headers UAPI: Sync files changed by new process_mrelease syscall and the removal of some compat entry points

To pick the changes in these csets:

  59ab844e ("compat: remove some compat entry points")
  dce49103 ("mm: wire up syscall process_mrelease")
  b48c7236 ("exit/bdflush: Remove the deprecated bdflush system call")

That add support for this new syscall in tools such as 'perf trace'.

For instance, this is now possible:

  # perf trace -v -e process_mrelease
  event qualifier tracepoint filter: (common_pid != 19351 && common_pid != 9112) && (id == 448)
  ^C#

That is the filter expression attached to the raw_syscalls:sys_{enter,exit}
tracepoints.

  $ grep process_mrelease tools/perf/arch/x86/entry/syscalls/syscall_64.tbl
  448    common  process_mrelease            sys_process_mrelease
  $

This addresses these perf build warnings:

 "Except for the xpram device driver removal it is all about fixes and
  cleanups.

   - Fix topology update on cpu hotplug, so notifiers see expected
     masks. This bug was uncovered with SCHED_CORE support.

   - Fix stack unwinding so that the correct number of entries are
     omitted like expected by common code. This fixes KCSAN selftests.

   - Add kmemleak annotation to stack_alloc to avoid false positive
     kmemleak warnings.

   - Avoid layering violation in common I/O code and don't unregister
     subchannel from child-drivers.

   - Remove xpram device driver for which no real use case exists since
     the kernel is 64 bit only. Also all hypervisors got required
     support removed in the meantime, which means the xpram device
     driver is dead code.

   - Fix -ENODEV handling of clp_get_state in our PCI code.

   - Enable KFENCE in debug defconfig.

   - Cleanup hugetlbfs s390 specific Kconfig dependency.

   - Quite a lot of trivial fixes to get rid of "W=1" warnings, and and

Servers happened below panic:

  Kernel version:5.4.56
  BUG: unable to handle page fault for address: 0000000000002c48
  RIP: 0010:__next_zones_zonelist+0x1d/0x40
  Call Trace:
    __alloc_pages_nodemask+0x277/0x310
    alloc_page_interleave+0x13/0x70

    __do_page_fault+0x288/0x500
    do_page_fault+0x30/0x110
    page_fault+0x3e/0x50

The reason for the panic is that MAX_NUMNODES is passed in the third
parameter in __alloc_pages_nodemask(preferred_nid).  So access to
zonelist->zoneref->zone_idx in __next_zones_zonelist will cause a panic.

In offset_il_node(), first_node() returns nid from pol->v.nodes, after
this other threads may chang pol->v.nodes before next_node().  This race
condition will let next_node return MAX_NUMNODES.  So put pol->nodes in
a local variable.

The race condition is between offset_il_node and cpuset_change_task_nodemask:

  CPU0:                                     CPU1:

        next_node(nid, pol->v.nodes)//return MAX_NUMNODES

In a memory pressure situation, I'm seeing the lockdep WARNING below.
Actually, this is similar to a known false positive which is already
addressed by commit 6dcde60e ("xfs: more lockdep whackamole with
kmem_alloc*").

This warning still persists because it's not from kmalloc() itself but
from an allocation for kmemleak object.  While kmalloc() itself suppress
the warning with __GFP_NOLOCKDEP, gfp_kmemleak_mask() is dropping the
flag for the kmemleak's allocation.

Allow __GFP_NOLOCKDEP to be passed to kmemleak's allocation, so that the
warning for it is also suppressed.

Commit f56ce412 ("mm: memcontrol: fix occasional OOMs due to
proportional memory.low reclaim") introduced a divide by zero corner
case when oomd is being used in combination with cgroup memory.low
protection.

When oomd decides to kill a cgroup, it will force the cgroup memory to
be reclaimed after killing the tasks, by writing to the memory.max file
for that cgroup, forcing the remaining page cache and reclaimable slab
to be reclaimed down to zero.

Previously, on cgroups with some memory.low protection that would result
in the memory being reclaimed down to the memory.low limit, or likely
not at all, having the page cache reclaimed asynchronously later.

With f56ce412 the oomd write to memory.max tries to reclaim all the
way down to zero, which may race with another reclaimer, to the point of
ending up with the divide by zero below.

This patch implements the obvious fix.

After fork, the child process will get incorrect (2x) hugetlb_usage.  If
a process uses 5 2MB hugetlb pages in an anonymous mapping,

	HugetlbPages:	   10240 kB

and then forks, the child will show,

	HugetlbPages:	   20480 kB

The reason for double the amount is because hugetlb_usage will be copied
from the parent and then increased when we copy page tables from parent
to child.  Child will have 2x actual usage.

Fix this by adding hugetlb_count_init in mm_init.

Previously, we noticed the one rpma example was failed[1] since commit
36f30e48 ("IB/core: Improve ODP to use hmm_range_fault()"), where it
will use ODP feature to do RDMA WRITE between fsdax files.

After digging into the code, we found hmm_vma_handle_pte() will still
return EFAULT even though all the its requesting flags has been
fulfilled.  That's because a DAX page will be marked as (_PAGE_SPECIAL |
PAGE_DEVMAP) by pte_mkdevmap().

Pull more power management updates from Rafael Wysocki:
 "These are mostly ARM cpufreq driver updates, including one new
  MediaTek driver that has just passed all of the reviews, with the
  addition of a revert of a recent intel_pstate commit, some core
  cpufreq changes and a DT-related update of the operating performance
  points (OPP) support code.

  Specifics:

   - Add new cpufreq driver for the MediaTek MT6779 platform called
     mediatek-hw along with corresponding DT bindings (Hector.Yuan).

   - Add DCVS interrupt support to the qcom-cpufreq-hw driver (Thara
     Gopinath).

   - Make the qcom-cpufreq-hw driver set the dvfs_possible_from_any_cpu
     policy flag (Taniya Das).

   - Blocklist more Qualcomm platforms in cpufreq-dt-platdev (Bjorn
     Andersson).

   - Make the vexpress cpufreq driver set the CPUFREQ_IS_COOLING_DEV
     flag (Viresh Kumar).

   - Add new cpufreq driver callback to allow drivers to register with
     the Energy Model in a consistent way and make several drivers use
     it (Viresh Kumar).

   - Change the remaining users of the .ready() cpufreq driver callback
     to move the code from it elsewhere and drop it from the cpufreq
     core (Viresh Kumar).

   - Revert recent intel_pstate change adding HWP guaranteed performance
     change notification support to it that led to problems, because the
     notification in question is triggered prematurely on some systems
     (Rafael Wysocki).

   - Convert the OPP DT bindings to DT schema and clean them up while at
     it (Rob Herring)"

Pull module updates from Jessica Yu:
 "The only main change I have for this round of updates is the modules
  MAINTAINERS update.

  As I find myself with less time to devote to upstream these days, Luis
  has kindly agreed to help maintain the module loader, to eventually
  transition to being the primary maintainer. Since Luis is already very
  involved upstream with experience maintaining various areas of the
  kernel including the kmod usermode helper, I think he is a great fit
  for this area of the kernel.

  Summary:

   - Add Luis Chamberlain as modules maintainer

   - Fix for .ctors sections in module linker script"
