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 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"
