Hi

Please consider this for inclusion into the testing tree.

This patchset introduces cpuidle infrastructure to POWER, prototyping
for pSeries, and also does a major refactoring of current x86 idle
power management and a cleanup of cpuidle infrastructure.

Earlier discussions on the same can be found at:

v7 --> http://lkml.org/lkml/2009/10/6/278
v6 --> http://lkml.org/lkml/2009/9/22/180
v5 --> http://lkml.org/lkml/2009/9/22/26
v4 --> http://lkml.org/lkml/2009/9/1/133
v3 --> http://lkml.org/lkml/2009/8/27/124
v2 --> http://lkml.org/lkml/2009/8/26/233
v1 --> http://lkml.org/lkml/2009/8/19/150


Changes in this version:
--------------------------------------

* Remove redundant poll_idle definition in arch/x86/kernel/process.c

* Prevent acpi_driver from registering when boot_option_idle_override
  is set and let cpuidle_default driver to take over in this case.

* Enable default_idle when power_save=off in POWER.

thanks,
arun
