Merge branch 'sched-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull scheduler fixes from Thomas Gleixner:
"This updates contains the following changes:
- Fix a signal handling regression in the bit wait functions.
- Avoid false positive warnings in the wakeup path.
- Initialize the scheduler root domain properly.
- Handle gtime calculations in proc/$PID/stat proper.
- Add more documentation for the barriers in try_to_wake_up().
- Fix a subtle race in try_to_wake_up() which might cause a task to
be scheduled on two cpus
- Compile static helper function only when it is used"
