Pull timer updates from Ingo Molnar:
 "The main changes in this cycle were:

   - clockevents state machine cleanups and enhancements (Viresh Kumar)

   - clockevents broadcast notifier horror to state machine conversion
     and related cleanups (Thomas Gleixner, Rafael J Wysocki)

   - clocksource and timekeeping core updates (John Stultz)

   - clocksource driver updates and fixes (Ben Dooks, Dmitry Osipenko,
     Hans de Goede, Laurent Pinchart, Maxime Ripard, Xunlei Pang)

   - y2038 fixes (Xunlei Pang, John Stultz)

   - NMI-safe ktime_get_raw_fast() and general refactoring of the clock
     code, in preparation to perf's per event clock ID support (Peter
     Zijlstra)

   - generic sched/clock fixes, optimizations and cleanups (Daniel
     Thompson)

   - clockevents cpu_down() race fix (Preeti U Murthy)"
