Pull locking updates from Ingo Molnar: - rwsem cleanups & optimizations/fixes: - Conditionally wake waiters in reader/writer slowpaths - Always try to wake waiters in out_nolock path - Add try_cmpxchg64() implementation, with arch optimizations - and use it to micro-optimize sched_clock_{local,remote}() - Various force-inlining fixes to address objdump instrumentation-check warnings - Add lock contention tracepoints: lock:contention_begin lock:contention_end - Misc smaller fixes & cleanups * tag 'locking-core-2022-05-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: sched/clock: Use try_cmpxchg64 in sched_clock_{local,remote} locking/atomic/x86: Introduce arch_try_cmpxchg64 locking/atomic: Add generic try_cmpxchg64 support futex: Remove a PREEMPT_RT_FULL reference. locking/qrwlock: Change "queue rwlock" to "queued rwlock" lockdep: Delete local_irq_enable_in_hardirq() locking/mutex: Make contention tracepoints more consistent wrt adaptive spinning locking: Apply contention tracepoints in the slow path locking: Add lock contention tracepoints locking/rwsem: Always try to wake waiters in out_nolock path locking/rwsem: Conditionally wake waiters in reader/writer slowpaths locking/rwsem: No need to check for handoff bit if wait queue empty lockdep: Fix -Wunused-parameter for _THIS_IP_ x86/mm: Force-inline __phys_addr_nodebug() x86/kvm/svm: Force-inline GHCB accessors task_stack, x86/cea: Force-inline stack helpers
