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

Browse source 
Pull timer updates from Thomas Gleixner:
 "The timers departement more or less proudly presents:

   - More Y2038 timekeeping work mostly in the core code. The work is
     slowly, but steadily targeting the actuall syscalls.

   - Enhanced timekeeping suspend/resume support by utilizing
     clocksources which do not stop during suspend, but are otherwise
     not the main timekeeping clocksources.

   - Make NTP adjustmets more accurate and immediate when the frequency
     is set directly and not incrementally.

   - Sanitize the overrung handing of posix timers

   - A new timer driver for Mediatek SoCs

   - The usual pile of fixes and updates all over the place"
