Pull locking updates from Ingo Molnar:
 "Locking primitives:
   - Micro-optimize percpu_{,try_}cmpxchg{64,128}_op() and
     {,try_}cmpxchg{64,128} on x86 (Uros Bizjak)
   - mutexes: extend debug checks in mutex_lock() (Yunhui Cui)
   - Misc cleanups (Uros Bizjak)

  Lockdep:
   - Fix might_fault() lockdep check of current->mm->mmap_lock (Peter
     Zijlstra)
   - Don't disable interrupts on RT in disable_irq_nosync_lockdep.*()
     (Sebastian Andrzej Siewior)
   - Disable KASAN instrumentation of lockdep.c (Waiman Long)
   - Add kasan_check_byte() check in lock_acquire() (Waiman Long)
   - Misc cleanups (Sebastian Andrzej Siewior)

  Rust runtime integration:
   - Use Pin for all LockClassKey usages (Mitchell Levy)
   - sync: Add accessor for the lock behind a given guard (Alice Ryhl)
   - sync: condvar: Add wait_interruptible_freezable() (Alice Ryhl)
   - sync: lock: Add an example for Guard:: Lock_ref() (Boqun Feng)

  Split-lock detection feature (x86):
   - Fix warning mode with disabled mitigation mode (Maksim Davydov)

  Locking events:
   - Add locking events for rtmutex slow paths (Waiman Long)
   - Add locking events for lockdep (Waiman Long)"
