This set required 4 additional patches to avoid errors.

Peter Zijlstra (4):
  futex,rt_mutex: Provide futex specific rt_mutex API
  futex: Remove rt_mutex_deadlock_account_*()
  futex: Rework inconsistent rt_mutex/futex_q state
  futex: Avoid violating the 10th rule of futex

Thomas Gleixner (6):
  futex: Replace pointless printk in fixup_owner()
  futex: Provide and use pi_state_update_owner()
  rtmutex: Remove unused argument from rt_mutex_proxy_unlock()
  futex: Use pi_state_update_owner() in put_pi_state()
  futex: Simplify fixup_pi_state_owner()
  futex: Handle faults correctly for PI futexes
