Subject: [GIT PULL] Power management fixes for v5.11-rc6

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.11-rc6

with top-most commit fef9c8d28e28a808274a18fbd8cc2685817fd62a

 PM: hibernate: flush swap writer after marking

on top of commit 6ee1d745b7c9fd573fba142a2efdad76a9f1cb04

 Linux 5.11-rc5

to receive power management fixes for 5.11-rc6.

These fix a deadlock in the "kexec jump" code and address a possible
hibernation image creation issue.

Specifics:

 - Fix a deadlock caused by attempting to acquire the same mutex
   twice in a row in the "kexec jump" code (Baoquan He).

 - Modify the hibernation image saving code to flush the unwritten
   data to the swap storage later so as to avoid failing to write the
   image signature which is possible in some cases (Laurent Badel).

Thanks!
