    Linus Torvalds authored
    Pull locking updates from Ingo Molnar:
     "The main changes in this cycle were:
    
       - a big round of FUTEX_UNLOCK_PI improvements, fixes, cleanups and
         general restructuring
    
       - lockdep updates such as new checks for lock_downgrade()
    
       - introduce the new atomic_try_cmpxchg() locking API and use it to
         optimize refcount code generation
    
       - ... plus misc fixes, updates and cleanups"
