Merge tag 'pm-5.11-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management fixes from Rafael Wysocki:
"Address a performance regression related to scale-invariance on x86
that may prevent turbo CPU frequencies from being used in certain
workloads on systems using acpi-cpufreq as the CPU performance scaling
driver and schedutil as the scaling governor"
* tag 'pm-5.11-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
cpufreq: ACPI: Update arch scale-invariance max perf ratio if CPPC is not there
cpufreq: ACPI: Extend frequency tables to cover boost frequencies
