[GIT PULL] Power management fixes for v5.10-rc2

[Rafael J. Wysocki]

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.10-rc2

with top-most commit dea47cf45a7f9bb94684830c47d4b259d5f8d6af

 Merge branches 'pm-cpuidle' and 'pm-sleep'

on top of commit 3650b228f83adda7e5ee532e2b90429c03f7b9ec

 Linux 5.10-rc1

to receive power management fixes for 5.10-rc2.

These fix a few issues related to running intel_pstate in the passive
mode with HWP enabled, correct the handling of the max_cstate module
parameter in intel_idle and make a few janitorial changes.

Specifics:

 - Modify Kconfig to prevent configuring either the "conservative"
   or the "ondemand" governor as the default cpufreq governor if
   intel_pstate is selected, in which case "schedutil" is the
   default choice for the default governor setting (Rafael Wysocki).

 - Modify the cpufreq core, intel_pstate and the schedutil governor
   to avoid missing updates of the HWP max limit when intel_pstate
   operates in the passive mode with HWP enabled (Rafael Wysocki).

 - Fix max_cstate module parameter handling in intel_idle for
   processor models with C-state tables coming from ACPI (Chen Yu).

 - Clean up assorted pieces of power management code (Jackie Zamow,
   Tom Rix, Zhang Qilong).

Thanks!
