Subject: [PATCH 0/3] rcu: Fix some rcu uses in extended quiescent state

Hi,

First patch lays the ground to fix rcu uses in dyntick idle mode
by splitting rcu extended qs state logic from tick nohz one.

The rest fixes the misuses that RCU has detected for me in x86.

I'll try to fix those Paul has detected in PowerPc.

Frederic Weisbecker (3):
  nohz: Split extended quiescent state handling from nohz switch
  x86: Enter rcu extended qs after idle notifier call
  x86: Call idle notifier after irq_enter()
