Subject[PATCH 3/4]: ACPI/ARM: Register for cpuidle_pm_idle in drivers/acpi/processor_idle.c and arch/arm/mach-kirkwood/cpuidle.c
* Arun R Bharadwaj <arun@linux.vnet.ibm.com> [2009-08-27 17:19:08]:

Set the idle routine to cpuidle_pm_idle after registering cpuidle
devices. Earlier pm_idle was assumed as the defualt idle loop by
cpuidle infrastructure. This is changed to an architecture independent
cpuidle_pm_idle.

There are 2 instances which are using cpuidle infrastructure currently.
This patch makes the change in both the places.
