[PATCH 04/89] sched/core: Remove unnecessary #include headers

Ingo Molnar
2017-02-06T13:58:01Z

Over the years sched/core.c accumulated over 50 #include lines,
40 of which are superfluous. (!)

Removing them decreases the preprocessed .c file (.i) size noticeably:

triton:~/tip> wc -l kernel/sched/core.i

Before: 76387 kernel/sched/core.i
After: 75896 kernel/sched/core.i
