linux-next: build failure after merge of the final tree (pm treerelated)

Hi Rafael,

After merging the final tree, today's linux-next build (powerpc
allnoconfig) failed like this:

mm/oom_kill.c: In function 'select_bad_process':
mm/oom_kill.c:326:5: error: implicit declaration of function '__thaw_task' [-Werror=implicit-function-declaration]

Caused by commit 23527e313ca5 ("PM / Freezer: Fix fallout of thaw_process()
-> __thaw_task() rename"). __thaw_task() is only declared id
CONFIG_FREEZER is set. Commit 944e192db53c ("freezer: rename thaw_process()
to __thaw_task() and simplify the implementation") removed the second
declaration of thaw_process() without replacing it ...

I have added this patch for today:

Subject: [PATCH] freezer: fix more fallout from the thaw_process rename

Commit 944e192db53c "freezer: rename thaw_process() to __thaw_task()
and simplify the implementation" did not create a !CONFIG_FREEZER version
of __thaw_task().
