    Pull locking updates from Ingo Molnar:
     "Here are the locking changes in this cycle:
    
       - rwsem unification and simpler micro-optimizations to prepare for
         more intrusive (and more lucrative) scalability improvements in
         v5.3 (Waiman Long)
    
       - Lockdep irq state tracking flag usage cleanups (Frederic
         Weisbecker)
    
       - static key improvements (Jakub Kicinski, Peter Zijlstra)
    
       - misc updates, cleanups and smaller fixes"
