Merge branch 'sched-wait-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull wait_var_event updates from Ingo Molnar:
"This introduces the new wait_var_event() API, which is a more flexible
waiting primitive than wait_on_atomic_t().
All wait_on_atomic_t() users are migrated over to the new API and
wait_on_atomic_t() is removed. The migration fixes one bug and should
result in no functional changes for the other usecases"
