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"

Merge tag 'kvmarm-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD

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

KVM: arm64: Disallow copying MTE to guest memory while KVM is dirty logging

Disallow copying MTE tags to guest memory while KVM is dirty logging, as
writing guest memory without marking the gfn as dirty in the memslot could
result in userspace failing to migrate the updated page. Ideally (maybe?),
KVM would simply mark the gfn as dirty, but there is no vCPU to work with,
and presumably the only use case for copy MTE tags _to_ the guest is when
restoring state on the target.

Put the page reference acquired by gfn_to_pfn_prot() if
kvm_vm_ioctl_mte_copy_tags() runs into ZONE_DEVICE memory. KVM's less-
than-stellar heuristics for dealing with pfn-mapped memory means that KVM
can get a page reference to ZONE_DEVICE memory.

ASoC: Updates for for v6.11

There are a lot of changes in here, though the big bulk of things is
cleanups and simplifications of various kinds which are internally
rather than externally visible. A good chunk of those are DT schema
conversions, but there's also a lot of changes in the code.

Highlights:

- Syncing of features between simple-audio-card and the two
audio-graph cards so there is no reason to stick with an older
driver.
- Support for specifying the order of operations for components within
cards to allow quirking for unusual systems.
- New support for Asahi Kasei AK4619, Cirrus Logic CS530x, Everest
Semiconductors ES8311, NXP i.MX95 and LPC32xx, Qualcomm LPASS v2.5
and WCD937x, Realtek RT1318 and RT1320 and Texas Instruments PCM5242.
