I found two examples with the last two patches but I suspect there are more bugs
waiting to be detected under other configs and/or archs.

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()
