Merge branch 'timers-urgent-for-linus' of git://git.kernel.org/pub/sc…

…m/linux/kernel/git/tip/tip

Pull timer fixes from Thomas Gleixner:
 "A set of small fixes:

   - Repair the ktime_get_coarse() functions so they actually deliver
     what they are supposed to: tick granular time stamps. The current
     code missed to add the accumulated nanoseconds part of the
     timekeeper so the resulting granularity was 1 second.

   - Prevent the tracer from infinitely recursing into time getter
     functions in the arm architectured timer by marking these functions
     notrace

   - Fix a trivial compiler warning caused by wrong qualifier ordering"
