    Pull RCU updates from Ingo Molnar:
     "The main RCU changes in this cycle are:
    
       - the combination of tree geometry-initialization simplifications and
         OS-jitter-reduction changes to expedited grace periods.  These two
         are stacked due to the large number of conflicts that would
         otherwise result.
    
       - privatize smp_mb__after_unlock_lock().
    
         This commit moves the definition of smp_mb__after_unlock_lock() to
         kernel/rcu/tree.h, in recognition of the fact that RCU is the only
         thing using this, that nothing else is likely to use it, and that
         it is likely to go away completely.
    
       - documentation updates.
    
       - torture-test updates.
    
       - misc fixes"
