Linus Torvalds b1456f6dc1 Updates for the time/timer core code: 
- Rework the initialization of the posix-timer kmem_cache and move the
     cache pointer into the timer_data structure to prevent false sharing.
 
   - Switch the alarmtimer code to lock guards.
 
   - Improve the CPU selection criteria in the per CPU validation of the
     clocksource watchdog to avoid arbitrary selections (or omissions) on
     systems with a small number of CPUs.
 
   - The usual cleanups and improvements
