* Arun R Bharadwaj <arun@xxxxxxxxxxxxxxxxxx> [2009-12-02 15:24:27]: In arch/powerpc/kernel/idle.c create a default_idle() routine by moving the failover condition of the cpu_idle() idle loop. This is needed by cpuidle infrastructure to call default_idle when other idle routines are not yet registered. Functionality remains the same, but the code is slightly moved around.
