This is the first version based on v5.18-rc1, so we need more tests than usual.

the companion branch topic/sof-dev-rebase was updated with tag sof-dev-rebase-20220408, still 150 patches to upstream.

mm/munlock: add lru_add_drain() to fix memcg_stat_test
ece369c 
Mike reports that LTP memcg_stat_test usually leads to

  memcg_stat_test 3 TINFO: Test unevictable with MAP_LOCKED
  memcg_stat_test 3 TINFO: Running memcg_process --mmap-lock1 -s 135168
  memcg_stat_test 3 TINFO: Warming up pid: 3460
  memcg_stat_test 3 TINFO: Process is still here after warm up: 3460
  memcg_stat_test 3 TFAIL: unevictable is 122880, 135168 expected

but may also lead to

  memcg_stat_test 4 TINFO: Test unevictable with mlock
  memcg_stat_test 4 TINFO: Running memcg_process --mmap-lock2 -s 135168
  memcg_stat_test 4 TINFO: Warming up pid: 4271
  memcg_stat_test 4 TINFO: Process is still here after warm up: 4271
  memcg_stat_test 4 TFAIL: unevictable is 122880, 135168 expected

or both.  A wee bit flaky.

follow_page_pte() used to have an lru_add_drain() per each page mlocked,
and the test came to rely on accurate stats.  The pagevec to be drained
is different now, but still covered by lru_add_drain(); and, never mind
the test, I believe it's in everyone's interest that a bulk faulting
interface like populate_vma_page_range() or faultin_vma_page_range()
should drain its local pagevecs at the end, to save others sometimes
needing the much more expensive lru_add_drain_all().

This does not absolutely guarantee exact stats - the mlocking task can
be migrated between CPUs as it proceeds - but it's good enough and the
tests pass.

mm/munlock: update Documentation/vm/unevictable-lru.rst
577e984 
Update Documentation/vm/unevictable-lru.rst to reflect the changes made
by the mm/munlock series: keeping an mlock_count instead of page_mlock()
(formerly try_to_munlock()) and munlock_vma_pages_all() etc.  Also make
other little updates or cleanups wherever noticed.

But, I apologize, this is already out of date, in that "folio" appears
nowhere: 5.18 will be in a transitional state from "page" to "folio",
and documenting its current mix of the two does not help to understand
"the Unevictable LRU".  Should be revisited when naming is more settled.

mm/munlock: protect the per-CPU pagevec by a local_lock_t
adb11e7 
The access to mlock_pvec is protected by disabling preemption via
get_cpu_var() or implicit by having preemption disabled by the caller
(in mlock_page_drain() case).  This breaks on PREEMPT_RT since
folio_lruvec_lock_irq() acquires a sleeping lock in this section.

Create struct mlock_pvec which consits of the local_lock_t and the
pagevec.  Acquire the local_lock() before accessing the per-CPU pagevec.
Replace mlock_page_drain() with a _local() version which is invoked on
the local CPU and acquires the local_lock_t and a _remote() version
which uses the pagevec from a remote CPU which offline.

mm: kfence: fix objcgs vector allocation
8f0b364 
If the kfence object is allocated to be used for objects vector, then
this slot of the pool eventually being occupied permanently since the
vector is never freed.  The solutions could be (1) freeing vector when
the kfence object is freed or (2) allocating all vectors statically.

Since the memory consumption of object vectors is low, it is better to
chose (2) to fix the issue and it is also can reduce overhead of vectors
allocating in the future.

mm,hwpoison: unmap poisoned page before invalidation
3149c79 
In some cases it appears the invalidation of a hwpoisoned page fails
because the page is still mapped in another process.  This can cause a
program to be continuously restarted and die when it page faults on the
page that was not invalidated.  Avoid that problem by unmapping the
hwpoisoned page when we find it.

Another issue is that sometimes we end up oopsing in finish_fault, if
the code tries to do something with the now-NULL vmf->page.  I did not
hit this error when submitting the previous patch because there are
several opportunities for alloc_set_pte to bail out before accessing
vmf->page, and that apparently happened on those systems, and most of
the time on other systems, too.

However, across several million systems that error does occur a handful
of times a day.  It can be avoided by returning VM_FAULT_NOPAGE which
will cause do_read_fault to return before calling finish_fault.

mm, kasan: fix __GFP_BITS_SHIFT definition breaking LOCKDEP
ada543a 
KASAN changes that added new GFP flags mistakenly updated
__GFP_BITS_SHIFT as the total number of GFP bits instead of as a shift
used to define __GFP_BITS_MASK.

This broke LOCKDEP, as __GFP_BITS_MASK now gets the 25th bit enabled
instead of the 28th for __GFP_NOLOCKDEP.

Update __GFP_BITS_SHIFT to always count KASAN GFP bits.

In the future, we could handle all combinations of KASAN and LOCKDEP to
occupy as few bits as possible.  For now, we have enough GFP bits to be
inefficient in this quick fix.

mm/damon: prevent activated scheme from sleeping by deactivated schemes
78049e9 
In the DAMON, the minimum wait time of the schemes decides whether the
kernel wakes up 'kdamon_fn()'.  But since the minimum wait time is
initialized to zero, there are corner cases against the original
objective.

For example, if we have several schemes for one target, and if the wait
time of the first scheme is zero, the minimum wait time will set zero,
which means 'kdamond_fn()' should wake up to apply this scheme.
However, in the following scheme, wait time can be set to non-zero.
Thus, the mininum wait time will be set to non-zero, which can cause
sleeping this interval for 'kdamon_fn()' due to one deactivated last
scheme.

This commit prevents making DAMON monitoring inactive state due to other
deactivated schemes.

I.e. now when madvise gets those behaviours as args, 'perf trace' will
be able to translate from the number to a human readable string and to
use the strings in tracepoint filter expressions.

Now one can trace systemwide asking to see backtraces to where those
MSRs are being read/written with:

  # perf trace -e msr:*_msr/max-stack=32/ --filter="msr>=IA32_U_CET && msr<=IA32_INT_SSP_TAB"
  ^C#

If we use -v (verbose mode) we can see what it does behind the scenes:

  # perf trace -v -e msr:*_msr/max-stack=32/ --filter="msr>=IA32_U_CET && msr<=IA32_INT_SSP_TAB"

perf tools: Stop depending on .git files for building PERF-VERSION-FILE
d4ff926 
This essentially reverts commit c72e3f0 ("tools/perf/build:
Speed up git-version test on re-make") and commit 4e666cd
("perf tools: Fix dependency for version file creation")

In commit c72e3f0 ("tools/perf/build: Speed up git-version test
on re-make"), a makefile dependency on .git/HEAD was added. The
background is that running PERF-VERSION-FILE is relatively slow, and
commands like "git describe" are particularly slow.

In commit 4e666cd ("perf tools: Fix dependency for version file
creation"), an additional dependency on .git/ORIG_HEAD was added, as
.git/HEAD may not change for "git reset --hard HEAD^" command. However,
depending on whether we're on a branch or not, a "git cherry-pick" may
not lead to the version being updated.

As discussed with the git community in [0], using git internal files for
dependencies is not reliable. Commit 4e666cd also breaks some build
scenarios [1].

As mentioned, c72e3f0 ("tools/perf/build: Speed up git-version
test on re-make") was added to speed up the build. However in commit
7572733 ("perf tools: Fix version kernel tag") we removed the
call to "git describe", so just revert Makefile.perf back to same as pre
c72e3f0 ("tools/perf/build: Speed up git-version test on
re-make") and the build should not be so slow, as below:

Pre 7572733:

  $> time util/PERF-VERSION-GEN
    PERF_VERSION = 5.17.rc8.g4e666cdb06ee

  real    0m0.110s
  user    0m0.091s

Post 7572733:

    PERF_VERSION = 5.17.rc8.g7572733b8499

  real    0m0.039s

[1] https://lore.kernel.org/linux-perf-users/[email protected]/T/#u

Committer testing:

After a fresh rebuild using 'make -C tools/perf O=/tmp/build/perf install-bin':

  $ perf -v
  perf version 5.17.g162f9db407b6

perf evlist: Rename cpus to user_requested_cpus
0df6ade 
evlist contains cpus and all_cpus. all_cpus is the union of the cpu maps
of all evsels.

For non-task targets, cpus is set to be cpus requested from the command
line, defaulting to all online cpus if no cpus are specified.

For an uncore event, all_cpus may be just CPU 0 or every online CPU.

This causes all_cpus to have fewer values than the cpus variable which
is confusing given the 'all' in the name.

To try to make the behavior clearer, rename cpus to user_requested_cpus
and add comments on the two struct variables.

perf cpumap: More cpu map reuse by merge.
da0bfb9 
perf_cpu_map__merge() will reuse one of its arguments if they are equal or
the other argument is NULL.

The arguments could be reused if it is known one set of values is a
subset of the other.

For example, a map of 0-1 and a map of just 0 when merged yields the map
of 0-1.

Currently a new map is created rather than adding a reference count to
the original 0-1 map.

7e2022a 
Convert the tracepoint.py file to python3 as many of the files in
tools/perf are already written in python3.

Committer testing:

…rnel/git/soc/soc

Pull ARM SoC fixes from Arnd BergmannL
 "The introduction of vmap-stack on 32-bit arm caused a regression on a
  few omap3/omap4 machines that pass a stack variable into a firmware
  interface.

  The early pre-ACPI AMD Seattle machines have been broken for a while,
  Ard Biesheuvel has a series to bring them back for now.

  A few machines with multiple DMA channels used on a device have the
  channels in the wrong order according to the binding, which causes a
  harmless warning. Reversing the order is easier than fixing the tools
  to suppress the warning"

All devices with nvme drivers have failures: kernel: nvme0: Admin Cmd(0x2), I/O Error (sct 0x0 / sc 0x2)

which is likely related to: https://lore.kernel.org/linux-nvme/[email protected]/T/#m14a43e0c73c589876d0cf20680c792e8d2ef5063

a patch is in works, but nothing is final: https://lore.kernel.org/linux-nvme/[email protected]/T/#t

Other than that, it looks fine.
