#     Pull locking updates from Borislav Petkov:
#      "Lots of cleanups and preparation. Highlights:
#     
#        - futex: Cleanup and remove runtime futex_cmpxchg detection
#     
#        - rtmutex: Some fixes for the PREEMPT_RT locking infrastructure
#     
#        - kcsan: Share owner_on_cpu() between mutex,rtmutex and rwsem and
#          annotate the racy owner->on_cpu access *once*.
#     
#        - atomic64: Dead-Code-Elemination"

#       locking/atomic: atomic64: Remove unusable atomic ops
#       futex: Fix additional regressions
#       locking: Allow to include asm/spinlock_types.h from linux/spinlock_types_raw.h
#       x86/mm: Include spinlock_t definition in pgtable.
#       locking: Mark racy reads of owner->on_cpu
#       locking: Make owner_on_cpu() into <linux/sched.h>
#       lockdep/selftests: Adapt ww-tests for PREEMPT_RT
#       lockdep/selftests: Skip the softirq related tests on PREEMPT_RT
#       lockdep/selftests: Unbalanced migrate_disable() & rcu_read_lock().
#       lockdep/selftests: Avoid using local_lock_{acquire|release}().
#       lockdep: Remove softirq accounting on PREEMPT_RT.
#       locking/rtmutex: Add rt_mutex_lock_nest_lock() and rt_mutex_lock_killable().
#       locking/rtmutex: Squash self-deadlock check for ww_rt_mutex.
#       locking: Remove rt_rwlock_is_contended().
#       sched: Trigger warning if ->migration_disabled counter underflows.
#       futex: Fix sparc32/m68k/nds32 build regression
#       futex: Remove futex_cmpxchg detection
#       futex: Ensure futex_atomic_cmpxchg_inatomic() is present
#       kernel/locking: Use a pointer in ww_mutex_trylock().
