* Arun R Bharadwaj <[email protected]> [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.
