Subject: [GIT PULL] Power management fixes for v6.18-rc4

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-6.18-rc4

with top-most commit 590c5cd10675a6ae49f6019502dec5c87aba07e4

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

on top of commit dcb6fa37fd7bc9c3d2b066329b0d27dedf8becaa

 Linux 6.18-rc3

to receive power management fixes for 6.18-rc4.

These fix three regressions, two recent ones and one introduced during
the 6.17 development cycle:

 - Add an exit latency check to the menu cpuidle governor in the case
   when it considers using a real idle state instead of a polling one to
   address a performance regression (Rafael Wysocki)

 - Revert an attempted cleanup of a system suspend code path that
   introduced a regression elsewhere (Samuel Wu)

 - Allow pm_restrict_gfp_mask() to be called multiple times in a row
   and adjust pm_restore_gfp_mask() accordingly to avoid having to play
   nasty games with these calls during hibernation (Rafael Wysocki)

Thanks!

Samuel Wu (1):
      Revert "PM: sleep: Make pm_wakeup_clear() call more clear"
