Hi Linus,

Please pull from the tag

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-7.3-rc1-2

with top-most commit 76854b339b3fbbc144f7ad6dd96e7495b94aab62

Merge branches 'pm-cpufreq' and 'pm-sleep'

on top of commit a5778046a02570fd23bdf0b48dce330237d1996c

Merge tag 'pm-7.3-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

to receive more power management updates for 7.3-rc1.

These fix two issues in the intel_rapl power capping driver, fix a
potential issue in the schedutil cpufreq governor on 32-bit systems,
fix a runtime PM issue related to failing system suspend, and update
the intel_pstate cpufreq driver:

- Fix a kernel panic during PMU unbind in the intel_rapl power capping
driver and sign-extend the PMU delta on counter wraparound in it to
avoid misreporting energy (Sumeet Pawnikar and Yifan Li)

- Unblock runtime PM when device prepare fails that was not done by
mistake (Shibo Zhu)

- Fix possible rate limit overflow on 32-bit systems in the schedutil
cpufreq governor (Hui Su)

- Consolidate HWP P-states initialization in the intel_pstate cpufreq
driver and make that driver avoid using the DESIRED_PERF HWP hint
when the Dynamic Efficiency Control (DEC) is enabled in the processor
to avoid inconsistent behavior (Rafael Wysocki)

Thanks!
