ASoC: Fixes for v6.12

A bunch of fixes here that came in during the merge window and the first
week of release, plus some new quirks and device IDs. There's nothing
major here, it's a bit bigger than it might've been due to there being
no fixes sent during the merge window due to your vacation.

Merge tag 'for-linus-non-x86' of git://git.kernel.org/pub/scm/virt/kvm/kvm

Pull kvm updates from Paolo Bonzini:
"These are the non-x86 changes (mostly ARM, as is usually the case).
The generic and x86 changes will come later"

ARM:

- New Stage-2 page table dumper, reusing the main ptdump
infrastructure

- FP8 support

- Nested virtualization now supports the address translation
(FEAT_ATS1A) family of instructions

- Add selftest checks for a bunch of timer emulation corner cases

- Fix multiple cases where KVM/arm64 doesn't correctly handle the
guest trying to use a GICv3 that wasn't advertised

- Remove REG_HIDDEN_USER from the sysreg infrastructure, making
things little simpler

- Prevent MTE tags being restored by userspace if we are actively
logging writes, as that's a recipe for disaster

- Correct the refcount on a page that is not considered for MTE tag
copying (such as a device)

- When walking a page table to split block mappings, synchronize only
at the end the walk rather than on every store

- Fix boundary check when transfering memory using FFA

- Fix pKVM TLB invalidation, only affecting currently out of tree
code but worth addressing for peace of mind

LoongArch:

- Revert qspinlock to test-and-set simple lock on VM.

- Add Loongson Binary Translation extension support.

- Add PMU support for guest.

- Enable paravirt feature control from VMM.

- Implement function kvm_para_has_feature().

RISC-V:

- Fix sbiret init before forwarding to userspace

- Don't zero-out PMU snapshot area before freeing data

- Allow legacy PMU access from guest

- Fix to allow hpmcounter31 from the guest"

KVM/arm64 updates for 6.12

* New features:

- Add a Stage-2 page table dumper, reusing the main ptdump
infrastructure, and allowing easier debugging of the our
page-table infrastructure

- Add FP8 support to the KVM/arm64 floating point handling.

- Add NV support for the AT family of instructions, which mostly
results in adding a page table walker that deals with most of the
complexity of the architecture.

* Improvements, fixes and cleanups:

- Add selftest checks for a bunch of timer emulation corner cases

- Fix the multiple of cases where KVM/arm64 doesn't correctly handle
the guest trying to use a GICv3 that isn't advertised

- Remove REG_HIDDEN_USER from the sysreg infrastructure, making
things little more simple

- Prevent MTE tags being restored by userspace if we are actively
logging writes, as that's a recipe for disaster

- Correct the refcount on a page that is not considered for MTE tag
copying (such as a device)

- Relax the synchronisation when walking a page table to split block
mappings, moving it at the end the walk, as there is no need to
perform it on every store.

- Fix boundary check when transfering memory using FFA

- Fix pKVM TLB invalidation, only affecting currently out of tree
code but worth addressing for peace of mind

: .
: Fix the multiple of cases where KVM/arm64 doesn't correctly
: handle the guest trying to use a GICv3 that isn't advertised.
:
: From the cover letter:
:
: "It recently appeared that, when running on a GICv3-equipped platform
: (which is what non-ancient arm64 HW has), *not* configuring a GICv3
: for the guest could result in less than desirable outcomes.
:
: We have multiple issues to fix:
:
: - for registers that *always* trap (the SGI registers) or that *may*
: trap (the SRE register), we need to check whether a GICv3 has been
: instantiated before acting upon the trap.
:
: - for registers that only conditionally trap, we must actively trap
: them even in the absence of a GICv3 being instantiated, and handle
: those traps accordingly.
:
: - finally, ID registers must reflect the absence of a GICv3, so that
: we are consistent.
:
: This series goes through all these requirements. The main complexity
: here is to apply a GICv3 configuration on the host in the absence of a
: GICv3 in the guest. This is pretty hackish, but I don't have a much
: better solution so far.
:
: As part of making wider use of of the trap bits, we fully define the
: trap routing as per the architecture, something that we eventually
: need for NV anyway."
