Pull timer updates - and a leftover fix - from Thomas Gleixner:
 "A rather large (commit wise) update from the timer side:

   - A bulk update to make compile tests work in the clocksource drivers

   - An overhaul of the h8300 timers

   - Some more Y2038 work

   - A few overflow prevention checks in the timekeeping/ntp code

   - The usual pile of fixes and improvements to the various
     clocksource/clockevent drivers and core code"

Also:
 "A single fix for the posix-clock poll code which did not make it into
  4.4"
