Merge branch 'core-locking-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull core locking updates from Ingo Molnar: "The biggest change is the MCS spinlock generalization changes from Tim Chen, Peter Zijlstra, Jason Low et al. There's also lockdep fixes/enhancements from Oleg Nesterov, in particular a false negative fix related to lockdep_set_novalidate_class() usage" * 'core-locking-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (22 commits) locking/mutex: Fix debug checks locking/mutexes: Add extra reschedule point locking/mutexes: Introduce cancelable MCS lock for adaptive spinning locking/mutexes: Unlock the mutex without the wait_lock locking/mutexes: Modify the way optimistic spinners are queued locking/mutexes: Return false if task need_resched() in mutex_can_spin_on_owner() locking: Move mcs_spinlock.h into kernel/locking/ m68k: Skip futex_atomic_cmpxchg_inatomic() test futex: Allow architectures to skip futex_atomic_cmpxchg_inatomic() test Revert "sched/wait: Suppress Sparse 'variable shadowing' warning" lockdep: Change lockdep_set_novalidate_class() to use _and_name lockdep: Change mark_held_locks() to check hlock->check instead of lockdep_no_validate lockdep: Don't create the wrong dependency on hlock->check == 0 lockdep: Make held_lock->check and "int check" argument bool locking/mcs: Allow architecture specific asm files to be used for contended case locking/mcs: Order the header files in Kbuild of each architecture in alphabetical order sched/wait: Suppress Sparse 'variable shadowing' warning hung_task/Documentation: Fix hung_task_warnings description locking/mcs: Allow architectures to hook in to contended paths locking/mcs: Micro-optimize the MCS code, add extra comments ...
