Linus Torvalds 4fd9435641 Updates for timers, timekeeping and related functionality:
- Core:
 
     - Make the takeover of a hrtimer based broadcast timer reliable during
       CPU hot-unplug. The current implementation suffers from a race which
       can lead to broadcast timer starvation in the worst case.
 
     - VDSO related cleanups and simplifications
 
     - Small cleanups and enhancements all over the place
 
   - PTP:
 
     - Replace the architecture specific base clock to clocksource, e.g. ART
       to TSC, conversion function with generic functionality to avoid
       exposing such internals to drivers and convert all existing drivers
       over. This also allows to provide functionality which converts the
       other way round in the core code based on the same parameter set.
 
     - Provide a function to convert CLOCK_REALTIME to the base clock to
       support the upcoming PPS output driver on Intel platforms.
 
   - Drivers:
 
     - A set of Device Tree bindings for new hardware
 
     - Cleanups and enhancements all over the place
