- 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

Pull timer core updates from Thomas Gleixner:
"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)
