Merge branch 'pm-sleep'

Merge system-wide power management updates for 6.8-rc1:

 - Fix possible deadlocks in the core system-wide PM code that occur if
   device-handling functions cannot be executed asynchronously during
   resune from system-wide suspend (Rafael J. Wysocki).

 - Clean up unnecessary local variable initializations in multiple
   places in the hibernation code (Wang chaodong, Li zeming).

 - Adjust core hibernation code to avoid missing wakeup events that
   occur after saving an image to persistent storage (Chris Feng).

 - Update hibernation code to enforce correct ordering during image
   compression and decompression (Hongchen Zhang).

 - Use kmap_local_page() instead of kmap_atomic() in copy_data_page()
   during hibernation and restore (Chen Haonan).

 - Adjust documentation and code comments to reflect recent task freezer
   changes (Kevin Hao).

 - Repair excess function parameter description warning in the
   hibernation image-saving code (Randy Dunlap).
