Subject: [GIT PULL] Power management fixes for v5.11-rc8

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.11-rc8

with top-most commit d11a1d08a082a7dc0ada423d2b2e26e9b6f2525c

 cpufreq: ACPI: Update arch scale-invariance max perf ratio if CPPC is not there

on top of commit 92bf22614b21a2706f4993b278017e437f7785b3

 Linux 5.11-rc7

to receive power management fixes for 5.11-rc8.

These 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.

Thanks!
