Here are a few updates for expedited RCU. Some were inspired by debates
with Paul while he was investigating the issue that got eventually
fixed by "rcu: Fix get_state_synchronize_rcu_full() GP-start detection".

Frederic Weisbecker (3):
  rcu/exp: Protect against early QS report
  rcu/exp: Remove confusing needless full barrier on task unblock
  rcu/exp: Remove needless CPU up quiescent state report
