Subject: [PATCH 0/5] sched: Split out kernel/sched/fair_balance.c, numa_balancing.c and syscalls.c, plus other updates

kernel/sched/core.c and fair.c have become a hodgepodge of scheduler
functionality that obscures core scheduling and fair-balancing
class scheduling functionality quite a bit.

Improve it all a bit by splitting syscall.c out of core.c, and
fair_balance.c and numa_balancing.c out of fair.c:

                                # of Lines of code
                                BEFORE => AFTER
                                ---------------
 kernel/sched/sched.h             3493 =>  3891
 kernel/sched/core.c             12067 => 10308
 kernel/sched/syscalls.c             - =>  1691

 kernel/sched/fair.c             13295 =>  5707
 kernel/sched/fair_balance.c         - =>  5103
 kernel/sched/numa_balancing.c       - =>  2277

 total                           49650 => 49765

This is only a first-approximation split.

Thanks,

    Ingo
