Merge tag 'pm-5.9-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management updates from Rafael Wysocki:
"These add a new CPU ID to the RAPL power capping driver and prevent
the ACPI processor idle driver from triggering RCU-lockdep complaints.
Specifics:
- Add support for the Lakefield chip to the RAPL power capping driver
(Ricardo Neri).
- Modify the ACPI processor idle driver to prevent it from triggering
RCU-lockdep complaints which has started to happen after recent
changes in that area (Peter Zijlstra)"
* tag 'pm-5.9-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
ACPI: processor: Take over RCU-idle for C3-BM idle
cpuidle: Allow cpuidle drivers to take over RCU-idle
ACPI: processor: Use CPUIDLE_FLAG_TLB_FLUSHED
ACPI: processor: Use CPUIDLE_FLAG_TIMER_STOP
powercap: RAPL: Add support for Lakefield
