   # 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
