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

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.

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)

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)"

cpufreq: Remove LATENCY_MULTIPLIER

cpufreq: Remove LATENCY_MULTIPLIER

The current LATENCY_MULTIPLIER which has been around for nearly 20 years
causes rate_limit_us to be always in ms range.

On M1 mac mini I get 50 and 56us transition latency, but due to the 1000
multiplier we end up setting rate_limit_us to 50 and 56ms, which gets
capped into 2ms and was 10ms before e13aa799c2a6 ("cpufreq: Change
default transition delay to 2ms")

On Intel I5 system transition latency is 20us but due to the multiplier
we end up with 20ms that again is capped to 2ms.

Given how good modern hardware and how modern workloads require systems
to be more responsive to cater for sudden changes in workload (tasks
sleeping/wakeup/migrating, uclamp causing a sudden boost or cap) and
that 2ms is quarter of the time of 120Hz refresh rate system, drop the
old logic in favour of providing 50% headroom.

rate_limit_us = 1.5 * latency.

I considered not adding any headroom which could mean that we can end up
with infinite back-to-back requests.

I also considered providing a constant headroom (e.g: 100us) assuming
that any h/w or f/w dealing with the request shouldn't require a large
headroom when transition_latency is actually high.

But for both cases I wasn't sure if h/w or f/w can end up being
overwhelmed dealing with the freq requests in a potentially busy system.
So I opted for providing 50% breathing room.

This is expected to impact schedutil only as the other user,
dbs_governor, takes the max(2*tick, transition_delay_us) and the former
was at least 2ms on 1ms TICK, which is equivalent to the max_delay_us
before applying this patch. For systems with TICK of 4ms, this value
would have almost always ended up with 8ms sampling rate.

For systems that report 0 transition latency, we still default to
returning 1ms as transition delay.

This helps in eliminating a source of latency for applying requests as
mentioned in [1]. For example if we have a 1ms tick, most systems will
miss sending an update at tick when updating the util_avg for a task/CPU
(rate_limit_us will be 2ms for most systems).
