Merge branch 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull core locking changes from Ingo Molnar: "Main changes: - jump label asm preparatory work for PowerPC (Anton Blanchard) - rwsem optimizations and cleanups (Davidlohr Bueso) - mutex optimizations and cleanups (Jason Low) - futex fix (Oleg Nesterov) - remove broken atomicity checks from {READ,WRITE}_ONCE() (Peter Zijlstra)" * 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: powerpc, jump_label: Include linux/jump_label.h to get HAVE_JUMP_LABEL define jump_label: Allow jump labels to be used in assembly jump_label: Allow asm/jump_label.h to be included in assembly locking/mutex: Further simplify mutex_spin_on_owner() locking: Remove atomicy checks from {READ,WRITE}_ONCE locking/rtmutex: Rename argument in the rt_mutex_adjust_prio_chain() documentation as well locking/rwsem: Fix lock optimistic spinning when owner is not running locking: Remove ACCESS_ONCE() usage locking/rwsem: Check for active lock before bailing on spinning locking/rwsem: Avoid deceiving lock spinners locking/rwsem: Set lock ownership ASAP locking/rwsem: Document barrier need when waking tasks locking/futex: Check PF_KTHREAD rather than !p->mm to filter out kthreads locking/mutex: Refactor mutex_spin_on_owner() locking/mutex: In mutex_spin_on_owner(), return true when owner changes
