This will hopefully make it easier to navigate the code without the need
to consult the full PM documentation.

Well, S0ix can occur in due to runtime PM as well.

That's FREEZE. Also called before restoring the hibenation image (QUIESCE).

That's THAW. Also called after failing the snapshot or restore (RECOVER).

after restoring the hibernation image is what I'd say. That's RESTORE.
