Pull locking updates from Ingo Molnar:
 "Futexes:

   - Add support for task local hash maps (Sebastian Andrzej Siewior,
     Peter Zijlstra)

   - Implement the FUTEX2_NUMA ABI, which feature extends the futex
     interface to be NUMA-aware. On NUMA-aware futexes a second u32 word
     containing the NUMA node is added to after the u32 futex value word
     (Peter Zijlstra)

   - Implement the FUTEX2_MPOL ABI, which feature extends the futex
     interface to be mempolicy-aware as well, to further refine futex
     node mappings and lookups (Peter Zijlstra)

  Locking primitives:

   - Misc cleanups (Andy Shevchenko, Borislav Petkov, Colin Ian King,
     Ingo Molnar, Nam Cao, Peter Zijlstra)

  Lockdep:

   - Prevent abuse of lockdep subclasses (Waiman Long)

   - Add number of dynamic keys to /proc/lockdep_stats (Waiman Long)

  Plus misc cleanups and fixes"
