Mixer quicks for the Pioneer DJM-A9 mixer was added in 5289d00 with
additional capture level values added to the common DJM array of values.
This breaks the existing DJM mixers however as alsa-utils relies on
enumeration of the actual mixer options based on the value array which
results in error when storing state.
This commit just separates the A9 values into a separate array and
references them in the corresponding mixer control.

The workaround for Dell machines to skip the pin-shutup for mic pins
introduced alc_headset_mic_no_shutup() that is replaced from the
generic snd_hda_shutup_pins() for certain codecs. The problem is that
the call is done unconditionally even if spec->no_shutup_pins is set.
This seems causing problems on other platforms like Lenovo.
This patch corrects the behavior and the driver honors always
spec->no_shutup_pins flag and skips alc_headset_mic_no_shutup() if
it's set.

This reverts commit 9bdd10d57a ("ASoC: ops: Shift tested values in
snd_soc_put_volsw() by +min"), and makes some additional related
updates.
There are two ways the platform_max could be interpreted; the maximum
register value, or the maximum value the control can be set to. The
patch moved from treating the value as a control value to a register
one. When the patch was applied it was technically correct as
snd_soc_limit_volume() also used the register interpretation. However,
even then most of the other usages treated platform_max as a
control value, and snd_soc_limit_volume() has since been updated to
also do so in commit fb9ad24485 ("ASoC: ops: add correct range
check for limiting volume"). That patch however, missed updating
snd_soc_put_volsw() back to the control interpretation, and fixing
snd_soc_info_volsw_range(). The control interpretation makes more
sense as limiting is typically done from the machine driver, so it is
appropriate to use the customer facing representation rather than the
internal codec representation. Update all the code to consistently use
this interpretation of platform_max.
Finally, also add some comments to the soc_mixer_control struct to
hopefully avoid further patches switching between the two approaches.

Dell XPS 13 7390 with the Realtek ALC3271 codec experiences
persistent humming noise when the power_save mode is enabled.
This issue occurs when the codec enters power saving mode,
leading to unwanted noise from the speakers.
This patch adds the affected model (PCI ID 0x1028:0x0962) to the
power_save denylist to ensure power_save is disabled by default,
preventing power-off related noise issues.
Steps to Reproduce
1. Boot the system with `snd_hda_intel` loaded.
2. Verify that `power_save` mode is enabled:
```sh
cat /sys/module/snd_hda_intel/parameters/power_save
````
output: 10 (default power save timeout)
3. Wait for the power save timeout
4. Observe a persistent humming noise from the speakers
5. Disable `power_save` manually:
```sh
echo 0 | sudo tee /sys/module/snd_hda_intel/parameters/power_save
````
6. Confirm that the noise disappears immediately.
This issue has been observed on my system, and this patch
successfully eliminates the unwanted noise. If other users
experience similar issues, additional reports would be helpful.

Using IS_REACHABLE() is somewhat questionable here anyway since it
leads to the input code not working when the HDA driver is builtin
but input is in a loadable module. Replace this with a hard compile-time
dependency on CONFIG_INPUT. In practice this won't chance much
other than solve the compiler error because it is rare to require

snd_seq_client_use_ptr() is supposed to return the snd_seq_client
object for the given client ID, and it tries to handle the module
auto-loading when no matching object is found. Although the module
handling is performed only conditionally with "!in_interrupt()", this
condition may be fragile, e.g. when the code is called from the ALSA
timer callback where the spinlock is temporarily disabled while the
irq is disabled. Then his doesn't fit well and spews the error about
sleep from invalid context, as complained recently by syzbot.
Also, in general, handling the module-loading at each time if no
matching object is found is really an overkill. It can be still
useful when performed at the top-level ioctl or proc reads, but it
shouldn't be done at event delivery at all.
For addressing the issues above, this patch disables the module
handling in snd_seq_client_use_ptr() in normal cases like event
deliveries, but allow only in limited and safe situations.
A new function client_load_and_use_ptr() is used for the cases where
the module loading can be done safely, instead.

"Ryan's been hard at work finding and fixing mm bugs in the arm64 code,
so here's a small crop of fixes for -rc5.
The main changes are to fix our zapping of non-present PTEs for
hugetlb entries created using the contiguous bit in the page-table
rather than a block entry at the level above. Prior to these fixes, we
were pulling the contiguous bit back out of the PTE in order to
determine the size of the hugetlb page but this is clearly bogus if
the thing isn't present and consequently both the clearing of the
PTE(s) and the TLB invalidation were unreliable.
Although the problem was found by code inspection, we really don't
want this sitting around waiting to trigger and the changes are CC'd
to stable accordingly.
Note that the diffstat looks a lot worse than it really is;
huge_ptep_get_and_clear() now takes a size argument from the core code
and so all the arch implementations of that have been updated in a
pretty mechanical fashion.

This reverts commit cc77e2ce18.
It was reported that adding ATA_QUIRK_NOLPM for Samsung SSD 870 QVO drives
breaks entering lower package states for certain systems.
It turns out that Samsung SSD 870 QVO actually has working LPM when using
a recent SSD firmware version.
The author of commit cc77e2ce18 ("ata: libata-core: Add ATA_QUIRK_NOLPM
for Samsung SSD 870 QVO drives") reported himself that only older SSD
firmware versions have broken LPM:
https://lore.kernel.org/stable/93c10d38-718c-459d-84a5-4d87680b4da7@debian.org/
Unfortunately, he did not specify which older firmware version he was using
which had broken LPM.
Let's revert this quirk, which has FW version field specified as NULL
(which means that it applies for all Samsung SSD 870 QVO firmware versions)
for now. Once the author reports which older firmware version(s) that are
broken, we can create a more fine grained quirk, which populates the FW
version field accordingly.

A VMM may send a non-fatal signal to its threads, including vCPU tasks,
at any time, and thus may signal vCPU tasks during KVM_RUN. If a vCPU
task receives the signal while its trying to spawn the huge page recovery
vhost task, then KVM_RUN will fail due to copy_process() returning
-ERESTARTNOINTR.
Rework call_once() to mark the call complete if and only if the called
function succeeds, and plumb the function's true error code back to the
call_once() invoker. This provides userspace with the correct, non-fatal
error code so that the VMM doesn't terminate the VM on -ENOMEM, and allows
subsequent KVM_RUN a succeed by virtue of retrying creation of the NX huge
page task.

- Fix crash from bad histogram entry
An error path in the histogram creation could leave an entry
in a link list that gets freed. Then when a new entry is added
it can cause a u-a-f bug. This is fixed by restructuring the code
so that the histogram is consistent on failure and everything is
cleaned up appropriately.
- Fix fprobe self test
The fprobe self test relies on no function being attached by ftrace.
BPF programs can attach to functions via ftrace and systemd now
does so. This causes those functions to appear in the enabled_functions
list which holds all functions attached by ftrace. The selftest also
uses that file to see if functions are being connected correctly.
It counts the functions in the file, but if there's already functions
in the file, it fails. Instead, add the number of functions in the file
at the start of the test to all the calculations during the test.
- Fix potential division by zero of the function profiler stddev
The calculated divisor that calculates the standard deviation of
the function times can overflow. If the overflow happens to land
on zero, that can cause a division by zero. Check for zero from
the calculation before doing the division.
TODO: Catch when it ever overflows and report it accordingly.
For now, just prevent the system from crashing.
