Deepthi Dharwar - Nov. 11, 2013, 5:35 a.m.
Currently pseries_idle cpuidle backend driver cannot be
built as a module due to dependencies. Therefore the driver has
to be built in. The dependency is around update_snooze_delay() defined
in cpuidle driver and called from kernel/sysfs.c.
This patch is removes all the module related code.
