Two fixes for the locking subsystem:

Browse source 
- Prevent an unconditional interrupt enable in a futex helper function
     which can be called from contexts which expect interrupts to stay
     disabled across the call.
 
   - Don't modify lockdep chain keys in the validation process as that
     causes chain inconsistency.
