Pull scheduler fixes from Thomas Gleixner:
 "This scheduler update provides:

   - The (hopefully) final fix for the vtime accounting issues which
     were around for quite some time

   - Use types known to user space in UAPI headers to unbreak user space
     builds

   - Make load balancing respect the current scheduling domain again
     instead of evaluating unrelated CPUs"

* 'sched-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  sched/headers/uapi: Fix linux/sched/types.h userspace compilation errors
  sched/fair: Fix load_balance() affinity redo path
  sched/cputime: Accumulate vtime on top of nsec clocksource
  sched/cputime: Move the vtime task fields to their own struct
  sched/cputime: Rename vtime fields
  sched/cputime: Always set tsk->vtime_snap_whence after accounting vtime
  vtime, sched/cputime: Remove vtime_account_user()
  Revert "sched/cputime: Refactor the cputime_adjust() code"
