Merge branch 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull locking updates from Ingo Molnar: "The main changes in this cycle are: - big rtmutex and futex cleanup and robustification from Thomas Gleixner - mutex optimizations and refinements from Jason Low - arch_mutex_cpu_relax() removal and related cleanups - smaller lockdep tweaks" * 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (23 commits) arch, locking: Ciao arch_mutex_cpu_relax() locking/lockdep: Only ask for /proc/lock_stat output when available locking/mutexes: Optimize mutex trylock slowpath locking/mutexes: Try to acquire mutex only if it is unlocked locking/mutexes: Delete the MUTEX_SHOW_NO_WAITER macro locking/mutexes: Correct documentation on mutex optimistic spinning rtmutex: Make the rtmutex tester depend on BROKEN futex: Simplify futex_lock_pi_atomic() and make it more robust futex: Split out the first waiter attachment from lookup_pi_state() futex: Split out the waiter check from lookup_pi_state() futex: Use futex_top_waiter() in lookup_pi_state() futex: Make unlock_pi more robust rtmutex: Avoid pointless requeueing in the deadlock detection chain walk rtmutex: Cleanup deadlock detector debug logic rtmutex: Confine deadlock logic to futex rtmutex: Simplify remove_waiter() rtmutex: Document pi chain walk rtmutex: Clarify the boost/deboost part rtmutex: No need to keep task ref for lock owner check rtmutex: Simplify and document try_to_take_rtmutex() ...
