Subject: [PATCH 0/4] PM / Freezer: Fix the semantics of thaw_processes() and
 thaw_kernel_threads()

With the introduction of thaw_kernel_threads(), we can now finally fix the
semantics of thawing tasks, in such a way as to be just the opposite of
how tasks are frozen. This opens up some opportunities for code cleanup
as well. This patchset implements both of these improvements.

This patchset applies on top of the patch posted at
