Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull timer updates from Thomas Gleixner:
 "The timer departement delivers:

   - more year 2038 rework

   - a massive rework of the arm achitected timer

   - preparatory patches to allow NTP correction of clock event devices
     to avoid early expiry

   - the usual pile of fixes and enhancements all over the place"
