Linus,
Please pull the latest locking/core git tree from:

# HEAD: cd27ccfc727e99352321c0c75012ab9c5a90321e jump_label: Refactor #ifdef of struct static_key
Changes in this cycle were:
- bitops & cpumask: - Always inline various generic helpers, to improve code generation, but also for instrumentation, found by noinstr validation. - Add a x86-specific cpumask_clear_cpu() helper to improve code generation
- atomics: - Fix atomic64_{read_acquire,set_release} fallbacks
- lockdep: - Fix /proc/lockdep output loop iteration for classes - Fix /proc/lockdep potential access to invalid memory - minor cleanups - Add Mark Rutland as reviewer for atomic primitives
- jump labels: - Clean up the code a bit
- misc: - Add __sched annotations to percpu rwsem primitives - Enable RT_MUTEXES on PREEMPT_RT by default - Stray v8086_mode() inlining fix, result of noinstr objtool validation
Thanks,
Ingo
------------------> Borislav Petkov (4): asm-generic/bitops: Always inline all bit manipulation helpers cpumask: Always inline helpers which use bit manipulation functions cpumask: Add a x86-specific cpumask_clear_cpu() helper x86/ptrace: Always inline v8086_mode() for instrumentation
Mark Rutland (2): MAINTAINERS: add myself as reviewer for atomics atomics: Fix atomic64_{read_acquire,set_release} fallbacks
Masahiro Yamada (2): jump_label: Avoid unneeded casts in STATIC_KEY_INIT_{TRUE,FALSE} jump_label: Refactor #ifdef of struct static_key
Minchan Kim (1): locking: Add missing __sched attributes
Sebastian Andrzej Siewior (2): locking/local_lock: Make the empty local_lock_*() function a macro. locking: Enable RT_MUTEXES by default on PREEMPT_RT.
Waiman Long (2): locking/lockdep: Avoid potential access of invalid memory in lock_class locking/lockdep: Iterate lock_classes directly when reading lockdep files
Xiu Jianfeng (1): lockdep: Use memset_startat() helper in reinit_class()
