you have tested the module? If not tested, please don't use the module.
We do want to make it a module. But for now that cannot be done due to
some other dependencies. This feature needs to be built in.
Thanks for the review.

To unsubscribe
This patch enables idle cpu on the powernv platform to hook on to the cpuidle
framework, if available, else call on to default idle platform
code.

This removes a lot of code duplicacy, thus making the code elegant.

As a part of pseries_idle backend driver cleanup to make
the code common to both pseries and powernv platforms, it
is necessary to move the backend-driver code to drivers/cpuidle.
As a pre-requisite for that, it is essential to move plpar_wrapper.h
to include/asm.
