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.

Merge tag 'pm-6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Merge tag 'pm-6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management updates from Rafael Wysocki:
"By the number of new lines of code, the most visible change here is
the addition of hybrid CPU capacity scaling support to the
intel_pstate driver. Next are the amd-pstate driver changes related to
the calculation of the AMD boost numerator and preferred core
detection.

As far as new hardware support is concerned, the intel_idle driver
will now handle Granite Rapids Xeon processors natively, the
intel_rapl power capping driver will recognize family 1Ah of AMD
processors and Intel ArrowLake-U chipos, and intel_pstate will handle
Granite Rapids and Sierra Forest chips in the out-of-band (OOB) mode.

Apart from the above, there is a usual collection of assorted fixes
and code cleanups in many places and there are tooling updates.

Specifics:

- Remove LATENCY_MULTIPLIER from cpufreq (Qais Yousef)

- Add support for Granite Rapids and Sierra Forest in OOB mode to the
intel_pstate cpufreq driver (Srinivas Pandruvada)

- Add basic support for CPU capacity scaling on x86 and make the
intel_pstate driver set asymmetric CPU capacity on hybrid systems
without SMT (Rafael Wysocki)

- Add missing MODULE_DESCRIPTION() macros to the powerpc cpufreq
driver (Jeff Johnson)

- Several OF related cleanups in cpufreq drivers (Rob Herring)

- Enable COMPILE_TEST for ARM drivers (Rob Herrring)

- Introduce quirks for syscon failures and use socinfo to get
revision for TI cpufreq driver (Dhruva Gole, Nishanth Menon)

- Minor cleanups in amd-pstate driver (Anastasia Belova, Dhananjay
Ugwekar)

- Minor cleanups for loongson, cpufreq-dt and powernv cpufreq drivers
(Danila Tikhonov, Huacai Chen, and Liu Jing)

- Make amd-pstate validate return of any attempt to update EPP
limits, which fixes the masking hardware problems (Mario
Limonciello)

- Move the calculation of the AMD boost numerator outside of
amd-pstate, correcting acpi-cpufreq on systems with preferred cores
(Mario Limonciello)

- Harden preferred core detection in amd-pstate to avoid potential
false positives (Mario Limonciello)

- Add extra unit test coverage for mode state machine (Mario
Limonciello)

- Fix an "Uninitialized variables" issue in amd-pstste (Qianqiang
Liu)

- Add Granite Rapids Xeon support to intel_idle (Artem Bityutskiy)

- Disable promotion to C1E on Jasper Lake and Elkhart Lake in
intel_idle (Kai-Heng Feng)

- Use scoped device node handling to fix missing of_node_put() and
simplify walking OF children in the riscv-sbi cpuidle driver
(Krzysztof Kozlowski)

- Remove dead code from cpuidle_enter_state() (Dhruva Gole)

- Change an error pointer to NULL to fix error handling in the
intel_rapl power capping driver (Dan Carpenter)

- Fix off by one in get_rpi() in the intel_rapl power capping driver
(Dan Carpenter)

- Add support for ArrowLake-U to the intel_rapl power capping driver
(Sumeet Pawnikar)

- Fix the energy-pkg event for AMD CPUs in the intel_rapl power
capping driver (Dhananjay Ugwekar)

- Add support for AMD family 1Ah processors to the intel_rapl power
capping driver (Dhananjay Ugwekar)

- Remove unused stub for saveable_highmem_page() and remove
deprecated macros from power management documentation (Andy
Shevchenko)

- Use ysfs_emit() and sysfs_emit_at() in "show" functions in the PM
sysfs interface (Xueqin Luo)

- Update the maintainers information for the
operating-points-v2-ti-cpu DT binding (Dhruva Gole)

- Drop unnecessary of_match_ptr() from ti-opp-supply (Rob Herring)

- Add missing MODULE_DESCRIPTION() macros to devfreq governors (Jeff
Johnson)

- Use devm_clk_get_enabled() in the exynos-bus devfreq driver (Anand
Moon)

- Use of_property_present() instead of of_get_property() in the
imx-bus devfreq driver (Rob Herring)

- Update directory handling and installation process in the pm-graph
Makefile and add .gitignore to ignore sleepgraph.py artifacts to
pm-graph (Amit Vadhavana, Yo-Jung Lin)

- Make cpupower display residency value in idle-info (Aboorva
Devarajan)

- Add missing powercap_set_enabled() stub function to cpupower (John
B. Wyatt IV)

- Add SWIG support to cpupower (John B. Wyatt IV)"
