Merge tag 'kvmarm-fixes-6.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD

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.

tools/x86/kcpuid: Parse subleaf ranges if provided

It's a common pattern in cpuid leaves to have the same bitfields format
repeated across a number of subleaves. Typically, this is used for
enumerating hierarchial structures like cache and TLB levels, CPU
topology levels, etc.

Modify kcpuid.c to handle subleaf ranges in the CSV file subleaves
column. For example, make it able to parse lines in the form:

# LEAF, SUBLEAVES, reg, bits, short_name , ...
0xb, 1:0, eax, 4:0, x2apic_id_shift , ...
0xb, 1:0, ebx, 15:0, domain_lcpus_count , ...
0xb, 1:0, ecx, 7:0, domain_nr , ...

This way, full output can be printed to the user.

tools/x86/kcpuid: Recognize all leaves with subleaves

cpuid.csv will be extended in further commits with all-publicly-known
CPUID leaves and bitfields. Thus, modify has_subleafs() to identify all
known leaves with subleaves.

Remove the redundant "is_amd" check since all x86 vendors already report
the maxium supported extended leaf at leaf 0x80000000 EAX register.

The extra mentioned leaves are:

- Leaf 0x12, Intel Software Guard Extensions (SGX) enumeration
- Leaf 0x14, Intel process trace (PT) enumeration
- Leaf 0x17, Intel SoC vendor attributes enumeration
- Leaf 0x1b, Intel PCONFIG (Platform configuration) enumeration
- Leaf 0x1d, Intel AMX (Advanced Matrix Extensions) tile information
- Leaf 0x1f, Intel v2 extended topology enumeration
- Leaf 0x23, Intel ArchPerfmonExt (Architectural PMU ext) enumeration
- Leaf 0x80000020, AMD Platform QoS extended features enumeration
- Leaf 0x80000026, AMD v2 extended topology enumeration

Set the 'max_subleaf' variable for all the newly marked leaves with extra
subleaves. Ideally, this should be fetched from the CSV file instead,
but the current kcpuid code architecture has two runs: one run to
serially invoke the cpuid instructions and save all the output in-memory,
and one run to parse this in-memory output through the CSV specification.

While parsing and saving bitfield names from the CSV file, an extra

now, but further commits will add a new CSV file with much more padding
for the bitfield's name column.

which includes signed/unsigned comparisons warnings.

tools/x86/kcpuid: Properly align long-description columns

When kcpuid is invoked with "--all --details", the detailed description
column is not properly aligned for all bitfield rows:

CPUID_0x4_ECX

tools/x86/kcpuid: Properly align long-description columns

When kcpuid is invoked with "--all --details", the detailed description
column is not properly aligned for all bitfield rows:

CPUID_0x4_ECX[0x0]:
cache_level : 0x1 - Cache Level ...
cache_self_init - Cache Self Initialization

This is due to differences in output handling between boolean single-bit
"bitflags" and multi-bit bitfields. For the former, the bitfield's value
is not outputted as it is implied to be true by just outputting the
bitflag's name in its respective line.

If long descriptions were requested through the --all parameter, properly
align the bitflag's description columns through extra tabs. With that,
the sample output above becomes:

CPUID_0x4_ECX[0x0]:
cache_level : 0x1 - Cache Level ...
cache_self_init - Cache Self Initialization
