Linus Torvalds 8596e589b7 Updates for timekeeping, timers and related drivers:
Core code:
 
   - Cure a couple of incorrectness issues in the posix CPU timer code to
     prevent that the tick dependency for NOHZ full is kept alive for no
     reason.
 
   - Avoid expensive double reprogramming of the clockevent device in
     hrtimer_start_range_ns().
 
   - Avoid pointless SMP function calls when the clock was set to avoid
     disturbing CPUs which do not have any affected timers queued.
 
   - Make the clocksource watchdog test work correctly when CONFIG_HZ is
     less than 100.
 
 Drivers:
 
   - Prefer the ARM architected timer over the Exynos timer which is way
     more expensive to access.
 
   - Add device tree bindings for new Ingenic SoCs
 
   - The usual improvements and cleanups all over the place
