[GIT PULL] Power management fixes for 7.4-rc3

[Rafael J. Wysocki (Intel)]

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-7.4-rc3

with top-most commit df42809bd599109660bd3f95e2e22330c80993df

 Merge branches 'pm-cpufreq' and 'pm-runtime'

on top of commit 7475ea8b58616b33c04afb976cf0fbaad9dd63fb

 Linux 7.4-rc2

to receive power management fixes for 7.4-rc3.

These address a few issues in the cpufreq core and drivers, including
issues actually seen in the field, a few issues related to runtime PM,
including a false-positive warning introduced relatively recently
and a long-standing defect in the runtime PM core code related to
autosuspend, and revert a problematic recent update of the intel_rapl
power capping driver.

Specifics:

 - Revert a recent update of the intel_rapl power capping driver that
   caused perf to return bogus values (Dennis Chen)

 - Fix the synchronization of boost state updates in cpufreq (Christian
   Loehle)

 - Fix issues related to system suspend-resume synchronization in the
   cpufreq core and intel_pstate driver (Rafael Wysocki)

 - Fix P-state index mismatch in extract_io() in the ACPI cpufreq driver
   on systems with defective _PSS (Li RongQing)

 - Fix issues related to target frequency caching in cpufreq (Rafael
   Wysocki)

 - Prevent a false-positive warning in pm_runtime_remove() introduced
   by a previous fix during the 7.0 development cycle (Zhou Minqiang)

 - Extend a recent improvement related to the handling of suppliers
   during device runtime-suspend to some previously missed cases in
   which it is relevant for consistency (Brian Norris)

 - Update runtime PM documentation to reflect new behavior after recent
   changes (Stanley Jhu)

 - Add last_busy timestamp updates for devices requested to resume from
   runtime suspend that are missing if those devices are not actually
   suspended (Rafael Wysocki)

Thanks!
