Linus Torvalds c5448d46b3 Updates for the time(rs) core subsystem: 
- Address the inconsistent shutdown sequence of per CPU clockevents on
     CPU hotplug, which onoly removed it from the core but failed to invoke
     the actual device driver shutdown callback. This keeps the timer
     active, which prevents power savings and causes pointless noise in
     virtualization.
 
   - Encapsulate the open coded access to the hrtimer clock base, which is a
     private implementation detail, so that the implementation can be
     changed without breaking a lot of usage sites.
 
   - Enhance the debug output of the clocksource watchdog to provide better
     information for analysis.
 
   - The usual set of cleanups and enhancements all over the place
