Earlier pm_idle function pointer would be set to default idle. Now a cpuidle_driver encapsulating the idle routine is cleanly registered for this using cpuidle_register_driver API. * Implemented a cpuidle driver for apm_cpu_idle() as part of APM BIOS driver. Earlier APM BIOS driver would flip pm_idle function pointer to apm_cpu_idle. * This patch series applies on 2.6.38, and was tested on x86 system with multiple sleep states. Goal: This patch series tries to achieve the goal of having cpuidle manage all idle routine for x86. It removes pm_idle function pointer which causes problems discussed at http://lkml.org/lkml/2009/8/28/43 and http://lkml.org/lkml/2009/8/28/50.
