  sched: clean up some control group code
  sched: constify sched.h
  sched: document profile=sleep requiring CONFIG_SCHEDSTATS
  sched: use show_regs() to improve __schedule_bug() output
  sched: clean up sched_domain_debug()
  sched: fix fastcall mismatch in completion APIs
  sched: fix sched_domain sysctl registration again
