Subject: [PATCH 0/3] powerpc (powernv and pseries) cpuidle driver improvmeents

Hi,

These are a few small improvements that came from doing an
optimisation pass over powerpc cpu idle paths.

Michael reminded me to cc the cpuidle maintainers. I think he
will take the patches through the powerpc tree, but any suggestion
or ack or nack would be welcome.

Thanks,
Nick

  cpuidle: powerpc: cpuidle set polling before enabling irqs
  cpuidle: powerpc: read mostly for common globals
  cpuidle: powerpc: no memory barrier after break from idle
