Pull memory model updates from Paul McKenney:
 "lkmm: Fix corner-case locking bug and improve documentation

  A simple but odd single-process litmus test acquires and immediately
  releases a lock, then calls spin_is_locked(). LKMM acts if it was a
  deadlock due to an assumption that spin_is_locked() will follow a
  spin_lock() or some other process's spin_unlock(). This litmus test
  manages to violate this assumption because the spin_is_locked()
  follows the same process's spin_unlock().

  This series fixes this bug, reorganizes and optimizes the lock.cat
  model, and updates documentation"
