Linus Torvalds 0a1d4434db Updates for timers, timekeeping and drivers:
- Core:
 
    - The timer_shutdown[_sync]() infrastructure:
 
      Tearing down timers can be tedious when there are circular
      dependencies to other things which need to be torn down. A prime
      example is timer and workqueue where the timer schedules work and the
      work arms the timer.
 
      What needs to prevented is that pending work which is drained via
      destroy_workqueue() does not rearm the previously shutdown
      timer. Nothing in that shutdown sequence relies on the timer being
      functional.
 
      The conclusion was that the semantics of timer_shutdown_sync() should
      be:
 
 	- timer is not enqueued
     	- timer callback is not running
     	- timer cannot be rearmed
 
      Preventing the rearming of shutdown timers is done by discarding rearm
      attempts silently. A warning for the case that a rearm attempt of a
      shutdown timer is detected would not be really helpful because it's
      entirely unclear how it should be acted upon. The only way to address
      such a case is to add 'if (in_shutdown)' conditionals all over the
      place. This is error prone and in most cases of teardown not required
      all.
 
    - The real fix for the bluetooth HCI teardown based on
      timer_shutdown_sync().
 
      A larger scale conversion to timer_shutdown_sync() is work in
      progress.
 
    - Consolidation of VDSO time namespace helper functions
 
    - Small fixes for timer and timerqueue
 
  - Drivers:
 
    - Prevent integer overflow on the XGene-1 TVAL register which causes
      an never ending interrupt storm.
 
    - The usual set of new device tree bindings
 
    - Small fixes and improvements all over the place
