    Pull futex fixes from Ingo Molnar:

     - Tighten up the sys_futex_requeue() ABI a bit, to disallow dissimilar
       futex flags and potential UaF access (Peter Zijlstra)

     - Fix UaF between futex_key_to_node_opt() and vma_replace_policy()
       (Hao-Yu Yang)

     - Clear stale exiting pointer in futex_lock_pi() retry path, which
       triggered a warning (and potential misbehavior) in stress-testing
       (Davidlohr Bueso)
