Now one can trace systemwide asking to see backtraces to where that MSR
is being read/written, see this example with a previous update:
# 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"
Using CPUID AuthenticAMD-25-21-0

The usermodehelper code uses two fake pointers for the two capability
cases: CAP_BSET for reading and writing 'usermodehelper_bset', and
CAP_PI to read and write 'usermodehelper_inheritable'.
This seems to be a completely unnecessary indirection, since we could
instead just use the pointers themselves, and never have to do any "if
this then that" kind of logic.
So just get rid of the fake pointer values, and use the real pointer
values instead.

The ppc64le_allmodconfig sets I2C_PASEMI=y and leaves COMPILE_TEST to
default to y and I2C_APPLE to default to m, running into a known
incompatible configuration that breaks the build [1]. Specifically,
a common dependency (i2c-pasemi-core.o in this case) cannot be used by
both builtin and module consumers.
Disable I2C_APPLE when I2C_PASEMI is a builtin to prevent this.

When user space updates the trip point there is a deadlock, which results
in caller gets blocked forever.
Commit 05eeee2b51 ("thermal/core: Protect sysfs accesses to thermal
operations with thermal zone mutex"), added a mutex for tz->lock in the
function trip_point_temp_store(). Hence, trip set callback() can't
call any thermal zone API as they are protected with the same mutex lock.
The callback here calling thermal_zone_device_enable(), which will result
in deadlock.
Move the thermal_zone_device_enable() to proc_thermal_pci_probe() to
avoid this deadlock.

Pull more s390 updates from Heiko Carstens:
- Add empty command line parameter handling stubs to kernel for all
command line parameters which are handled in the decompressor. This
avoids invalid "Unknown kernel command line parameters" messages from
the kernel, and also avoids that these will be incorrectly passed to
user space. This caused already confusion, therefore add the empty
stubs
- Add missing phys_to_virt() handling to machine check handler
- Introduce and use a union to be used for zcrypt inline assemblies.
This makes sure that only a register wide member of the union is
passed as input and output parameter to inline assemblies, while
usual C code uses other members of the union to access bit fields of
it
- Add and use a READ_ONCE_ALIGNED_128() macro, which can be used to
atomically read a 128-bit value from memory. This replaces the
(mis-)use of the 128-bit cmpxchg operation to do the same in cpum_sf
code. Currently gcc does not generate the used lpq instruction if
__READ_ONCE() is used for aligned 128-bit accesses, therefore use
this s390 specific helper
- Simplify machine check handler code if a task needs to be killed
because of e.g. register corruption due to a machine malfunction
- Perform CPU reset to clear pending interrupts and TLB entries on an
already stopped target CPU before delegating work to it
- Generate arch/s390/boot/vmlinux.map link map for the decompressor,
when CONFIG_VMLINUX_MAP is enabled for debugging purposes
- Fix segment type handling for dcssblk devices. It incorrectly always
returned type "READ/WRITE" even for read-only segements, which can
result in a kernel panic if somebody tries to write to a read-only
device
- Sort config S390 select list again
- Fix two kprobe reenter bugs revealed by a recently added kprobe kunit
test

Drivers:
- use IRQ flags from fwnode when available
- abx80x: nvmem support
- brcmstb-waketimer: add non-wake alarm support
- ingenic: provide CLK32K clock
- isl12022: cleanups
- moxart: switch to using gpiod API
- pcf85363: allow setting quartz load
- pm8xxx: cleanups and support for setting time

When a reset notify IPC message is received, the ISR schedules a work
function and passes the ISHTP device to it via a global pointer
ishtp_dev. If ish_probe() fails, the devm-managed device resources
including ishtp_dev are freed, but the work is not cancelled, causing a
use-after-free when the work function tries to access ishtp_dev. Use
devm_work_autocancel() instead, so that the work is automatically
cancelled if probe fails.

If snd_ctl_add() fails in aureon_add_controls(), it immediately returns
and leaves ice->gpio_mutex locked. ice->gpio_mutex locks in
snd_ice1712_save_gpio_status and unlocks in
snd_ice1712_restore_gpio_status(ice).
It seems that the mutex is required only for aureon_cs8415_get(),
so snd_ice1712_restore_gpio_status(ice) can be placed
just after that. Compile tested only.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

The headset jack works better with model=alc283-dac-wcaps. Without this
option, the headset insertion (separate physical jack) may not be handled
correctly (re-insertion is required).
It seems that it follows the "Intel Reference Board" defaults.

ASoC: Fixes for v6.3
Almost all of this is driver specific fixes and new IDs that have come
in during the merge window. A good chunk of them are simple ones from
me which came about due to a bunch of Mediatek Chromebooks being enabled
in KernelCI, there's more where that came from.
We do have one small feature added to the PCM core by Claudiu Beznea in
order to allow the sequencing required to resolve a noise issue with the
Microchip PDMC driver.
