    Linus Torvalds authored
    Pull RCU updates from Ingo Molnar:
     "The biggest RCU changes in this cycle were:
    
       - Convert RCU's BUG_ON() and similar calls to WARN_ON() and similar.
    
       - Replace calls of RCU-bh and RCU-sched update-side functions to
         their vanilla RCU counterparts. This series is a step towards
         complete removal of the RCU-bh and RCU-sched update-side functions.
    
         ( Note that some of these conversions are going upstream via their
           respective maintainers. )
    
       - Documentation updates, including a number of flavor-consolidation
         updates from Joel Fernandes.
    
       - Miscellaneous fixes.
    
       - Automate generation of the initrd filesystem used for rcutorture
         testing.
    
       - Convert spin_is_locked() assertions to instead use lockdep.
    
         ( Note that some of these conversions are going upstream via their
           respective maintainers. )
    
       - SRCU updates, especially including a fix from Dennis Krein for a
         bag-on-head-class bug.
    
       - RCU torture-test updates"
