Subject: [PATCH 0/4 v2] rcu: Detect rcu uses under extended quiescent state, and fix some

In this second version:

- rebase against latest rcu/dev branch of Paul's tree
- handle tiny RCU
- put acks

Frederic Weisbecker (4):
  rcu: Detect uses of rcu read side in extended quiescent states
  nohz: Split extended quiescent state handling from nohz switch
  x86: Don't call idle notifier inside rcu extended QS
  x86: Call idle_exit() after irq_enter()
