Merge branch 'fortglx/4.12/time' of https://git.linaro.org/people/john.stultz/linux into timers/core
Pull timekeeping changes from John Stultz:
Main changes are the initial steps of Nicoli's work to make the clockevent
timers be corrected for NTP adjustments. Then a few smaller fixes that
I've queued, and adding Stephen Boyd to the maintainers list for
timekeeping.
