    Merge branch 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip · 92400b8c
    Linus Torvalds authored
    Pull locking updates from Ingo Molnar:
    
     - Lots of tidying up changes all across the map for Linux's formal
       memory/locking-model tooling, by Alan Stern, Akira Yokosawa, Andrea
       Parri, Paul E. McKenney and SeongJae Park.
    
       Notable changes beyond an overall update in the tooling itself is the
       tidying up of spin_is_locked() semantics, which spills over into the
       kernel proper as well.
    
     - qspinlock improvements: the locking algorithm now guarantees forward
       progress whereas the previous implementation in mainline could starve
       threads indefinitely in cmpxchg() loops. Also other related cleanups
       to the qspinlock code (Will Deacon)
    
     - misc smaller improvements, cleanups and fixes all across the locking
       subsystem
