#     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
