Subject: [GIT PULL] Power management fixes for v5.8-rc3

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.8-rc3

with top-most commit 0e3fb2a128d81bc5baee76dddcc8ddbc8ccae95c

 Merge branches 'pm-cpufreq' and 'pm-cpuidle'

on top of commit 48778464bb7d346b47157d21ffde2af6b2d39110

 Linux 5.8-rc2

to receive power management fixes for 5.8-rc3.

These fix a recent regression that broke suspend-to-idle on some
x86 systems, fix the intel_pstate driver to correctly let the
platform firmware control CPU performance in some cases and
add __init annotations to a couple of functions.

Specifics:

 - Make sure that the _TIF_POLLING_NRFLAG is clear before entering
   the last phase of suspend-to-idle to avoid wakeup issues on some
   x86 systems (Chen Yu, Rafael Wysocki).

 - Cover one more case in which the intel_pstate driver should let
   the platform firmware control the CPU frequency and refuse to
   load (Srinivas Pandruvada).

 - Add __init annotations to 2 functions in the power management
   core (Christophe JAILLET).

Thanks!
