Subject: [PATCH 0/4] x86/cpuidle fixes and optimization

This is the x86 part of a cpuidle series I posted a few time ago. There
is a fix by Peter (Not-yet-signed-off-by btw.), the rest is comment and
optimizations.

Frederic Weisbecker (3):
  x86: Add a comment about the "magic" behind shadow sti before mwait
  x86: Remove __current_clr_polling() from mwait_idle()
  x86: Remove the current_clr_polling() call upon mwait exit

Peter Zijlstra (1):
  x86: Fix CPUIDLE_FLAG_IRQ_ENABLE leaking timer reprogram
