- Fix percpu-rwsem contention tracepoints
- Simplify debugging Kconfig dependencies
- Update/clarify the documentation of atomic primitives
- Misc cleanups
* tag 'locking-core-2024-03-11' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
locking/rtmutex: Use try_cmpxchg_relaxed() in mark_rt_mutex_waiters()
locking/x86: Implement local_xchg() using CMPXCHG without the LOCK prefix
locking/percpu-rwsem: Trigger contention tracepoints only if contended
locking/rwsem: Make DEBUG_RWSEMS and PREEMPT_RT mutually exclusive
locking/rwsem: Clarify that RWSEM_READER_OWNED is just a hint
locking/mutex: Simplify <linux/mutex.h>
locking/qspinlock: Fix 'wait_early' set but not used warning
locking/atomic: scripts: Clarify ordering of conditional atomics
