ASoC: Fixes for v6.19

We've been quite busy with fixes since the merge window, though not in
any particularly exciting ways - the standout thing is the fix for _SX
controls which were broken by a change to how we do clamping, otherwise
it's all fairly run of the mill fixes and quirks.

Merge tag 's390-6.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Heiko Carstens:

- Provide a new interface for dynamic configuration and deconfiguration
of hotplug memory, allowing with and without memmap_on_memory
support. This makes the way memory hotplug is handled on s390 much
more similar to other architectures

- Remove compat support. There shouldn't be any compat user space
around anymore, therefore get rid of a lot of code which also doesn't
need to be tested anymore

- Add stackprotector support. GCC 16 will get new compiler options,
which allow to generate code required for kernel stackprotector
support

- Merge pai_crypto and pai_ext PMU drivers into a new driver. This
removes a lot of duplicated code. The new driver is also extendable
and allows to support new PMUs

- Add driver override support for AP queues

- Rework and extend zcrypt and AP trace events to allow for tracing of
crypto requests

- Support block sizes larger than 65535 bytes for CCW tape devices

- Since the rework of the virtual kernel address space the module area
and the kernel image are within the same 4GB area. This eliminates
the need of weak per cpu variables. Get rid of
ARCH_MODULE_NEEDS_WEAK_PER_CPU

- Various other small improvements and fixes

s390: Add stackprotector support

Stackprotector support was previously unavailable on s390 because by
default compilers generate code which is not suitable for the kernel:
the canary value is accessed via thread local storage, where the address
of thread local storage is within access registers 0 and 1.

Using those registers also for the kernel would come with a significant
performance impact and more complicated kernel entry/exit code, since
access registers contents would have to be exchanged on every kernel entry
and exit.

With the upcoming gcc 16 release new compiler options will become available
which allow to generate code suitable for the kernel. [1]

Compiler option -mstack-protector-guard=global instructs gcc to generate
stackprotector code that refers to a global stackprotector canary value via
symbol __stack_chk_guard. Access to this value is guaranteed to occur via
larl and lgrl instructions.

Furthermore, compiler option -mstack-protector-guard-record generates a
section containing all code addresses that reference the canary value.

To allow for per task canary values the instructions which load the address
of __stack_chk_guard are patched so they access a lowcore field instead: a
per task canary value is available within the task_struct of each task, and
is written to the per-cpu lowcore location on each context switch.

Also add sanity checks and debugging option to be consistent with other
kernel code patching mechanisms.

Full debugging output can be enabled with the following kernel command line
options:

debug_stackprotector
bootdebug
ignore_loglevel
earlyprintk
dyndbg="file stackprotector.c +p"

Example debug output:

stackprot: 0000021e402d4eda: c010005a9ae3 -> c01f00070240

where "<insn address>: <old insn> -> <new insn>".

Merge branch 'compat-removal'

Heiko Carstens says:

====================

Remove s390 compat support to allow for code simplification and especially
reduced test effort. To the best of our knowledge there aren't any 31 bit
binaries out in the world anymore that would matter for newer kernels or
newer distributions.

Distributions do not provide compat packages since quite some time or even
have CONFIG_COMPAT disabled.

Instead of adding deprecation warnings to config option, or adding kernel
messages, just remove the code. Deprecation warnings haven't proven to be
useful. If it turns out there is still a reason to keep the compat support
this series can be reverted at any time in the future.

s390: Remove compat support

There shouldn't be any 31 bit code around anymore that matters.
Remove the compat layer support required to run 31 bit code.

Reason for removal is code simplification and reduced test effort.

Note that this comes without any deprecation warnings added to config
options, or kernel messages, since most likely those would be ignored
anyway.

If it turns out there is still a reason to keep the compat layer this
can be reverted at any time in the future.

Merge branch 'pai-pmu-merge'

Thomas Richter says:

====================

The PAI PMUs pai_crypto and pai_ext both operate on memory
mapped counters supported by z16 and follow on machines.
These memory mapped counters have a lot in common, like:
- validation, installing and removing events
- starting and stopping events
- retrieving counter values
- collecting sample data.

However both PMU drivers have slightly different parameters,
for example:
- different mapped memory size
- different number of supported counters
- different counter numbers and names
- different bits in the CR0 register
- different anchor address in lowcore

Due to these different parameters, two independent
PMUs have been developed. However both PMU drivers
have very much in common and most of the PMU call back
functions look very similar and are sometimes identical.

This patch set combines both independent PMU device drivers
perf_pai_crypto.c and per_pai_ext.c into one device driver.
The new device driver operations on a table which contains
the different parameters and uses common functions for
event operations.

Result is one PAI PMU driver which supports both PMUs.
It is also extendable to support new PAI PMUs.
