Subject: [PATCH v2 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.

v2: Interchanged the ordering of patches 1 and 2 and transferred a small
    comment between them. No code changes.

      PM/Hibernate: Thaw kernel threads in hibernation_snapshot() in error/test path
