Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.16-rc3

with top-most commit 7803516dbe26518115408d53a500ccb4d6a7d1c7

 Merge branch 'pm-sleep'

on top of commit 136057256686de39cc3a07c2e39ef6bc43003ff6

 Linux 5.16-rc2

to receive power management fixes for 5.16-rc3.

These address 3 issues in the intel_pstate driver and fix 2 problems
related to hibernation.

Specifics:

 - Make intel_pstate work correctly on Ice Lake server systems with
   out-of-band performance control enabled (Adamos Ttofari).

 - Fix EPP handling in intel_pstate during CPU offline and online in
   the active mode (Rafael Wysocki).

 - Make intel_pstate support ITMT on asymmetric systems with
   overclocking enabled (Srinivas Pandruvada).

 - Fix hibernation image saving when using the user space interface
   based on the snapshot special device file (Evan Green).

 - Make the hibernation code release the snapshot block device using
   the same mode that was used when acquiring it (Thomas Zeitlhofer).

Thanks!
