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
