Linus Torvalds ebd326ce72 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
