Merge branch 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux

Pull ACPI & power management update from Len Brown:
 "Re-write of the turbostat tool.
     lower overhead was necessary for measuring very large system when
     they are very idle.

  IVB support in intel_idle
     It's what I run on my IVB, others should be able to also:-)

  ACPICA core update
     We have found some bugs due to divergence between Linux and the
     upstream ACPICA base.  Most of these patches are to reduce that
     divergence to reduce the risk of future bugs.

  Some cpuidle updates, mostly for non-Intel
     More will be coming, as they depend on this part.

  Some thermal management changes needed by non-ACPI systems.

  Some _OST (OS Status Indication) updates for hot ACPI hot-plug."
