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.

s390/pci: Migrate s390 IRQ logic to IRQ domain API

s390 is one of the last architectures using the legacy API for setup and
teardown of PCI MSI IRQs. Migrate the s390 IRQ allocation and teardown
to the MSI parent domain API. For details, see:

https://lore.kernel.org/lkml/20221111120501.026511281@linutronix.de

In detail, create an MSI parent domain for each PCI domain. When a PCI
device sets up MSI or MSI-X IRQs, the library creates a per-device IRQ
domain for this device, which is used by the device for allocating and
freeing IRQs.

The per-device domain delegates this allocation and freeing to the
parent-domain. In the end, the corresponding callbacks of the parent
domain are responsible for allocating and freeing the IRQs.

The allocation is split into two parts:
- zpci_msi_prepare() is called once for each device and allocates the
required resources. On s390, each PCI function has its own airq
vector and a summary bit, which must be configured once per function.
This is done in prepare().
- zpci_msi_alloc() can be called multiple times for allocating one or
more MSI/MSI-X IRQs. This creates a mapping between the virtual IRQ
number in the kernel and the hardware IRQ number.

Freeing is split into two counterparts:
- zpci_msi_free() reverts the effects of zpci_msi_alloc() and
- zpci_msi_teardown() reverts the effects of zpci_msi_prepare(). This is
called once when all IRQs are freed before a device is removed.

Since the parent domain in the end allocates the IRQs, the hwirq
encoding must be unambiguous for all IRQs of all devices. This is
achieved by encoding the hwirq using the devfn and the MSI index.

Merge series from Vishwaroop A <va@nvidia.com>:

This patch series addresses timeout handling issues in the Tegra QSPI driver
that occur under high system load conditions. We've observed that when CPUs
are saturated (due to error injection, RAS firmware activity, or general CPU
contention), QSPI interrupt handlers can be delayed, causing spurious transfer
failures even though the hardware completed the operation successfully.

These changes have been tested in production environments under various high
load scenarios including RAS testing and CPU saturation workloads.

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

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>".
