KVM/arm64 fixes for 6.12, take #1

- Fix pKVM error path on init, making sure we do not change critical
system registers as we're about to fail

- Make sure that the host's vector length is at capped by a value
common to all CPUs

- Fix kvm_has_feat*() handling of "negative" features, as the current
code is pretty broken

- Promote Joey to the status of official reviewer, while James steps
down -- hopefully only temporarly

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.

This simp

drm/xe/xe2: Introduce identity map for compressed pat for vram

Xe2+ has unified compression (exactly one compression mode/format),
where compression is now controlled via PAT at PTE level.
This simplifies KMD operations, as it can now decompress freely
without concern for the buffer's original compression format—unlike DG2,
which had multiple compression formats and thus required copying the
raw CCS state during VRAM eviction. In addition mixed VRAM and system
memory buffers were not supported with compression enabled.

On Xe2 dGPU compression is still only supported with VRAM, however we
can now support compression with VRAM and system memory buffers,
with GPU access being seamless underneath. So long as when doing
VRAM -> system memory the KMD uses compressed -> uncompressed,
to decompress it. This also allows CPU access to such buffers,
assuming that userspace first decompress the corresponding
pages being accessed.
If the pages are already in system memory then KMD would have already
decompressed them. When restoring such buffers with sysmem -> VRAM
the KMD can't easily know which pages were originally compressed,
so we always use uncompressed -> uncompressed here.
With this it also means we can drop all the raw CCS handling on such
platforms (including needing to allocate extra CCS storage).

In order to support this we now need to have two different identity
mappings for compressed and uncompressed VRAM.
In this patch, we set up the additional identity map for the VRAM with
compressed pat_index. We then select the appropriate mapping during
migration/clear. During eviction (vram->sysmem), we use the mapping
from compressed -> uncompressed. During restore (sysmem->vram), we need
the mapping from uncompressed -> uncompressed.
Therefore, we need to have two different mappings for compressed and
uncompressed vram. We set up an additional identity map for the vram
with compressed pat_index.
We then select the appropriate mapping during migration/clear.

v2: Formatting nits, Updated code to match recent changes in
xe_migrate_prepare_vm(). (Matt)

v3: Move identity map loop to a helper function. (Matt Brost)

drm/xe/migrate: Add kunit to test clear functionality

This test verifies if the main and ccs data are cleared during bo creation.
The motivation to use Kunit instead of IGT is that, although we can verify
whether the data is zero following bo creation,
we cannot confirm whether the zero value after bo creation is the result of
our clear function or simply because the initial data present was zero.

v2: Updated the mutex_lock and unlock logic,
Changed out_unlock to out_put. (Matt)

v3: Added missing dma_fence_put(). (Nirmoy)

drm/xe/kunit: Simplify xe_migrate live tests code layout

The test case logic is implemented by the functions compiled as
part of the core Xe driver module and then exported to build and
register the test suite in the live test module.

But we don't need to export individual test case functions, we may
just export the entire test suite. And we don't need to register
this test suite in a separate file, it can be done in the main
file of the live test module.
