Pull pin control fixes from Linus Walleij:
 "There is an ACPI stubs fix which is ACKed by the ACPI maintainer for
  merging through my tree.

  One item stand out and that is that I delete the <linux/sdb.h> header
  that is used by nothing. I deleted this subsystem (through the GPIO
  tree) a while back so I feel responsible for tidying up the floor.

  Other than that it is the usual mistakes, a bit noisy around build
  issue and Kconfig then driver fixes.

  Specifics:

   - Fix some stubs causing compile issues for ACPI.

   - Fix some wakeups on AMD IRQs shared between GPIO and SCI.

   - Fix a build warning in the Tegra driver.

   - Fix a Kconfig issue in the Qualcomm driver.

   - Add a missing include the RALink driver.

   - Return a valid type for the Apple pinctrl IRQs.

   - Implement some Qualcomm SDM845 dual-edge errata.

   - Remove the unused <linux/sdb.h> header. (The subsystem was once
     deleted by the pinctrl maintainer...)

   - Fix a duplicate initialized in the Tegra driver.

   - Fix register offsets for UFS and SDC in the Qualcomm SM8350 driver"

 - Remove -mstack-guard and -mstack-size compile options when building
   vdso binaries. This can happen when CONFIG_VMAP_STACK is disabled and

   exceptions. Also remove the not needed -nostdlib option.

Recently to prevent issues with SECCOMP_RET_KILL and similar signals
being changed before they are delivered SA_IMMUTABLE was added.

Unfortunately this broke debuggers[1][2] which reasonably expect
to be able to trap synchronous SIGTRAP and SIGSEGV even when
the target process is not configured to handle those signals.

Add force_exit_sig and use it instead of force_fatal_sig where
historically the code has directly called do_exit.  This has the
implementation benefits of going through the signal exit path
(including generating core dumps) without the danger of allowing
userspace to ignore or change these signals.

This avoids userspace regressions as older kernels exited with do_exit
which debuggers also can not intercept.

In the future is should be possible to improve the quality of
implementation of the kernel by changing some of these force_exit_sig
calls to force_fatal_sig.  That can be done where it matters on
a case-by-case basis with careful analysis.

when it is not safe to let userspace know about the signal until the

If trace_seq becomes full, trace_seq_vprintf() no longer consumes
arguments from va_list, making va_list out of sync with format
processing by trace_check_vprintf().

This causes va_arg() in trace_check_vprintf() to return wrong
positional argument, which results into a WARN_ON_ONCE() hit.

ftrace_stress_test from LTP triggers this situation.

Fix it by explicitly avoiding further use if va_list at the point
when it's consistency can no longer be guaranteed.

Pull zstd fixes from Nick Terrell:
 "Fix stack usage on parisc & improve code size bloat

  This contains three commits:

   1. Fixes a minor unused variable warning reported by Kernel test
      robot [0].

   2. Improves the reported code bloat (-88KB / 374KB) [1] by outlining
      some functions that are unlikely to be used in performance
      sensitive workloads.

   3. Fixes the reported excess stack usage on parisc [2] by removing
      -O3 from zstd's compilation flags. -O3 triggered bugs in the
      hppa-linux-gnu gcc-8 compiler. -O2 performance is acceptable:
      neutral compression, about -1% decompression speed. We also reduce
      code bloat (-105KB / 374KB).

  After this our code bloat is cut from 374KB to 105KB with gcc-11. If
  we wanted to cut the remaining 105KB we'd likely have to trade
  signicant performance, so I want to say that this is enough for now.

  We should be able to get further gains without sacrificing speed, but
  that will take some significant optimization effort, and isn't
  suitable for a quick fix. I've opened an upstream issue [3] to track
  the code size, and try to avoid future regressions, and improve it in
  the long term"

After the update to zstd-1.4.10 passing -O3 is no longer necessary to
get good performance from zstd. Using the default optimization level -O2
is sufficient to get good performance.

I've measured no significant change to compression speed, and a ~1%
decompression speed loss, which is acceptable.

This fixes the reported parisc -Wframe-larger-than=1536 errors [0]. The
gcc-8-hppa-linux-gnu compiler performed very poorly with -O3, generating
stacks that are ~3KB. With -O2 these same functions generate stacks in
the < 100B, completely fixing the problem. Function size deltas are
listed below:

ZSTD_compressBlock_fast_extDict_generic: 3800 -> 68
ZSTD_compressBlock_fast: 2216 -> 40
ZSTD_compressBlock_fast_dictMatchState: 1848 ->  64
ZSTD_compressBlock_doubleFast_extDict_generic: 3744 -> 76
ZSTD_fillDoubleHashTable: 3252 -> 0
ZSTD_compressBlock_doubleFast: 5856 -> 36
ZSTD_compressBlock_doubleFast_dictMatchState: 5380 -> 84
ZSTD_copmressBlock_lazy2: 2420 -> 72

Additionally, this improves the reported code bloat [1]. With gcc-11
bloat-o-meter shows an 80KB code size improvement:

```
> ../scripts/bloat-o-meter vmlinux.old vmlinux
add/remove: 31/8 grow/shrink: 24/155 up/down: 25734/-107924 (-82190)
Total: Before=6418562, After=6336372, chg -1.28%
```

Compared to before the zstd-1.4.10 update we see a total code size
regression of 105KB, down from 374KB at v5.16-rc1:

```
> ../scripts/bloat-o-meter vmlinux.old vmlinux

`zstd_opt.c` contains the match finder for the highest compression
levels. These levels are already very slow, and are unlikely to be used
in the kernel. If they are used, they shouldn't be used in latency
sensitive workloads, so slowing them down shouldn't be a big deal.

This saves 188 KB of the 288 KB regression reported by Geert Uytterhoeven [0].
I've also opened an issue upstream [1] so that we can properly tackle
the code size issue in `zstd_opt.c` for all users, and can hopefully
remove this hack in the next zstd version we import.

The variable `litLengthSum` is only used by an `assert()`, so when
asserts are disabled the compiler doesn't see any usage and warns.

This issue is already fixed upstream by PR #2838 [0]. It was reported
by the Kernel test robot in [1].

Another approach would be to change zstd's disabled `assert()`
definition to use the argument in a disabled branch, instead of
ignoring the argument. I've avoided this approach because there are
some small changes necessary to get zstd to build, and I would
want to thoroughly re-test for performance, since that is slightly
changing the code in every function in zstd. It seems like a
trivial change, but some functions are pretty sensitive to small
changes. However, I think it is a valid approach that I would
like to see upstream take, so I've opened Issue #2868 to attempt
this upstream.

Lastly, I've chosen not to use __maybe_unused because all code
in lib/zstd/ must eventually be upstreamed. Upstream zstd can't
use __maybe_unused because it isn't portable across all compilers.

Pull setattr idmapping fix from Christian Brauner:
 "This contains a simple fix for setattr. When determining the validity
  of the attributes the ia_{g,u}id fields contain the value that will be
  written to inode->i_{g,u}id. When the {g,u}id attribute of the file
  isn't altered and the caller's fs{g,u}id matches the current {g,u}id
  attribute the attribute change is allowed.

  The value in ia_{g,u}id does already account for idmapped mounts and
  will have taken the relevant idmapping into account. So in order to
  verify that the {g,u}id attribute isn't changed we simple need to
  compare the ia_{g,u}id value against the inode's i_{g,u}id value.

  This only has any meaning for idmapped mounts as idmapping helpers are
  idempotent without them. And for idmapped mounts this really only has
  a meaning when circular idmappings are used, i.e. mappings where e.g.
  id 1000 is mapped to id 1001 and id 1001 is mapped to id 1000. Such
  ciruclar mappings can e.g. be useful when sharing the same home
  directory between multiple users at the same time.

  Before this patch we could end up denying legitimate attribute changes
  and allowing invalid attribute changes when circular mappings are
  used. To even get into this situation the caller must've been
  privileged both to create that mapping and to create that idmapped
  mount.

  This hasn't been seen in the wild anywhere but came up when expanding
  the fstest suite during work on a series of hardening patches. All
  idmapped fstests pass without any regressions and we're adding new
  tests to verify the behavior of circular mappings.

  The new tests can be found at [1]"
