    Pull locking fixes from Ingo Molnar:

     - Fix FUT_OFF_MMSHARED futex hashing bug that can cause
       missed wakeups or spurious wakeups on futex-waiting
       tasks (Jann Horn)

     - Fix lockdep context tracking bug in the deferred hrtimer
       rearming entry code, which causes a lockdep chain leak
       that will eventually turn lockdep off (Mikhail Gavrilov)
