Subject: [PATCH v1 0/2] cpufreq: ACPI: Address performance regression related to scale-invariance

Hi All,

These 2 patches address a performance regression related to scale-invariance
found by Michael and analyzed by Giovanni (see the patch from Giovanni at
https://lore.kernel.org/linux-pm/20210203135321.12253-2-ggherdovich@suse.cz/).

Patch [1/2] is a replacement for the one mentioned above (it was posted without
a changelog and tested somewhat) and patch [2/2] takes care of systems without
CPPC on top of that.

Please see the patch changelogs for details and let me know if you have any
concerns.

Thanks!
