Merge branch 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull locking changes from Ingo Molnar: "Various updates: - Futex scalability improvements: remove page lock use for shared futex get_futex_key(), which speeds up 'perf bench futex hash' benchmarks by over 40% on a 60-core Westmere. This makes anon-mem shared futexes perform close to private futexes. (Mel Gorman) - lockdep hash collision detection and fix (Alfredo Alvarez Fernandez) - lockdep testing enhancements (Alfredo Alvarez Fernandez) - robustify lockdep init by using hlists (Andrew Morton, Andrey Ryabinin) - mutex and csd_lock micro-optimizations (Davidlohr Bueso) - small x86 barriers tweaks (Michael S Tsirkin) - qspinlock updates (Waiman Long)" * 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (25 commits) locking/csd_lock: Use smp_cond_acquire() in csd_lock_wait() locking/csd_lock: Explicitly inline csd_lock*() helpers futex: Replace barrier() in unqueue_me() with READ_ONCE() locking/lockdep: Detect chain_key collisions locking/lockdep: Prevent chain_key collisions tools/lib/lockdep: Fix link creation warning tools/lib/lockdep: Add tests for AA and ABBA locking tools/lib/lockdep: Add userspace version of READ_ONCE() tools/lib/lockdep: Fix the build on recent kernels locking/qspinlock: Move __ARCH_SPIN_LOCK_UNLOCKED to qspinlock_types.h locking/mutex: Allow next waiter lockless wakeup locking/pvqspinlock: Enable slowpath locking count tracking locking/qspinlock: Use smp_cond_acquire() in pending code locking/pvqspinlock: Move lock stealing count tracking code into pv_queued_spin_steal_lock() locking/mcs: Fix mcs_spin_lock() ordering futex: Remove requirement for lock_page() in get_futex_key() futex: Rename barrier references in ordering guarantees locking/atomics: Update comment about READ_ONCE() and structures locking/lockdep: Eliminate lockdep_init() locking/lockdep: Convert hash tables to hlists ...
