Pull sound fixes from Takashi Iwai:
 "This became a slightly large collection of changes, partly because
  I've been off in the last weeks. Most of changes are small and
  scattered while a bit big change is found in HD-audio Realtek codec
  driver; it's a very device-specific fix that has been long wanted, so
  I decided to pick up although it's in the middle RC.

  Some highlights:

   - A new guard ioctl for ALSA rawmidi API to avoid the misuse of the
     new timestamp framing mode; it's for a regression fix

   - HD-audio: a revert of the 5.15 change that might work badly, new
     quirks for Lenovo Legion & co, a follow-up fix for CS8409

   - ASoC: lots of SOF-related fixes, fsl component fixes, corrections
     of mediatek drivers

   - USB-audio: fix for the PM resume

   - FireWire: oxfw and motu fixes"

The hrtimer callback pcsp_do_timer() prepares rearming of the timer with
hrtimer_forward(). hrtimer_forward() is intended to provide a mechanism to
forward the expiry time of the hrtimer by a multiple of the period argument
so that the expiry time greater than the time provided in the 'now'
argument.

pcsp_do_timer() invokes hrtimer_forward() with the current timer expiry
time as 'now' argument. That's providing a periodic timer expiry, but is
not really robust when the timer callback is delayed so that the resulting
new expiry time is already in the past which causes the callback to be
invoked immediately again. If the timer is delayed then the back to back
invocation is not really making it better than skipping the missed
periods. Sound is distorted in any case.

Use hrtimer_forward_now() which ensures that the next expiry is in the
future. This prevents hogging the CPU in the timer expiry code and allows
later on to remove hrtimer_forward() from the public interfaces.

Compiling sb_watchdog needs to clearly define SIBYTE_HDR_FEATURES.
In arch/mips/sibyte/Platform like:

                -DSIBYTE_HDR_FEATURES=SIBYTE_HDR_FMASK_1250_112x_ALL

Otherwise, SIBYTE_HDR_FEATURES is SIBYTE_HDR_FMASK_ALL.
SIBYTE_HDR_FMASK_ALL is mean:

 #define SIBYTE_HDR_FMASK_ALL  SIBYTE_HDR_FMASK_1250_ALL | SIBYTE_HDR_FMASK_112x_ALL \

Commit 9d682ea6 ("vboxsf: Fix the check for the old binary
mount-arguments struct") was meant to fix a build error due to sign
mismatch in 'char' and the use of character constants, but it just moved
the error elsewhere, in that on some architectures characters and signed
and on others they are unsigned, and that's just how the C standard
works.

The proper fix is a simple "don't do that then".  The code was just
being silly and odd, and it should never have cared about signed vs
unsigned characters in the first place, since what it is testing is not
four "characters", but four bytes.

And the way to compare four bytes is by using "memcmp()".

Which compilers will know to just turn into a single 32-bit compare with
a constant, as long as you don't have crazy debug options enabled.

If the 'perf iostat' user specifies two or more iio_root_ports and also
specifies the cpu(s) by -C which is not *connected to all* the above iio
ports, the iostat_print_metric() will run into trouble:

For example:

  $ perf iostat list
  S0-uncore_iio_0<0000:16>
  S1-uncore_iio_0<0000:97> # <--- CPU 1 is located in the socket S0

  $ perf iostat 0000:16,0000:97 -C 1 -- ls
  port 	Inbound Read(MB)	Inbound Write(MB)	Outbound Read(MB)	Outbound
  Write(MB) ../perf-iostat: line 12: 104418 Segmentation fault
  (core dumped) perf stat --iostat$DELIMITER$*

The core-dump stack says, in the above corner case, the returned
(struct perf_counts_values *) count will be NULL, and the caller
iostat_print_metric() apparently doesn't not handle this case.

  433	struct perf_counts_values *count = perf_counts(evsel->counts, die, 0);
  434
  435	if (count->run && count->ena) {
  (gdb) p count
  $1 = (struct perf_counts_values *) 0x0

The deeper reason is that there are actually no statistics from the user
specified pair "iostat 0000:X, -C (disconnected) Y ", but let's fix it with
minimum cost by adding a NULL check in the user space.

An iostate use case like "perf iostat 0000:16,0000:97 -- ls" should be
implemented to work in system-wide mode to ensure that the output from
print_header() is consistent with the user documentation perf-iostat.txt,
rather than incorrectly assuming that the kernel does not support it:

 Error:
 The sys_perf_event_open() syscall returned with 22 (Invalid argument) \
 for event (uncore_iio_0/event=0x83,umask=0x04,ch_mask=0xF,fc_mask=0x07/).
 /bin/dmesg | grep -i perf may provide additional information.

This error is easily fixed by assigning system-wide mode by default
for IOSTAT_RUN only when the target cpu_list is unspecified.

If there is no configuration file at first, the user can write any pair
of "key.subkey=value" to the newly created configuration file, while
value validation against a valid configurable key is *deferred* until
the next execution or the implied execution of "perf config ... ".

For example:

  $ rm ~/.perfconfig
  $ perf config call-graph.dump-size=65529
  $ cat ~/.perfconfig
  # this file is auto-generated.
  [call-graph]
 	dump-size = 65529
  $ perf config call-graph.dump-size=2048
  callchain: Incorrect stack dump size (max 65528): 65529
  Error: wrong config key-value pair call-graph.dump-size=65529

The user might expect that the second value 2048 is valid and can be
updated to the configuration file, but the error message is very
confusing because the first value 65529 is not reported as an error
during the last configuration.

It is recommended not to change the current behavior of delayed
validation (as more effort is needed), but to refine the original error
message to *clearly indicate* that the cause of the error is the
configuration file.

This test occasionally fails on aarch64 when a sample is taken in
free@plt and it fails with "Bytes read differ from those read by
objdump".

This is because that symbol is near a section boundary in the elf file.
Despite the -z option to always output zeros, objdump uses
bfd_map_over_sections() to iterate through the elf file so it doesn't
see outside of the sections where these zeros are and can't print them.

For example this boundary proceeds free@plt in libc with a gap of 48
bytes between .plt and .text:

  objdump -d -z --start-address=0x23cc8 --stop-address=0x23d08 libc-2.30.so

Taking a sample in free@plt is very rare because it is so small, but the
test can be forced to fail almost every time on any platform by linking
the test with a shared library that has a single empty function and
calling it in a loop.

The fix is to zero the buffers so that when there is a jump in the
addresses output by objdump, zeros are already filled in between.

To ensure the stack frames are on the stack tail calls optimizations
need to be inhibited. If your compiler supports an attribute use it,
otherwise use an asm volatile barrier.

The barrier fix was suggested here:
https://lore.kernel.org/lkml/20201028081123.GT2628@hirez.programming.kicks-ass.net/
Tested with an optimized clang build and by forcing the asm barrier
route with an optimized clang build.

A GCC bug tracking a proper disable_tail_calls is:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97831

Fixes: 9ae1e990 ("perf tools: Remove broken __no_tail_call
       attribute")

v2. is a rebase. The original fix patch generated quite a lot of
    discussion over the right place for the fix:
    https://lore.kernel.org/lkml/20201114000803.909530-1-irogers@google.com/
    The patch reflects my preference of it being near the use, so that
    future code cleanups don't break this somewhat special usage.

Pull io_uring fixes from Jens Axboe:
 "This one looks a bit bigger than it is, but that's mainly because 2/3
  of it is enabling IORING_OP_CLOSE to close direct file descriptors.

  We've had a few folks using them and finding it confusing that the way
  to close them is through using -1 for file update, this just brings
  API symmetry for direct descriptors. Hence I think we should just do
  this now and have a better API for 5.15 release. There's some room for
  de-duplicating the close code, but we're leaving that for the next
  merge window.

  Outside of that, just small fixes:

   - Poll race fixes (Hao)

   - io-wq core dump exit fix (me)

   - Reschedule around potentially intensive tctx and buffer iterators
     on teardown (me)
