[PATCH 0/3] cpuidle: avoid module usage in non-modular code

This series of commits is a part of a larger project to ensure people don't reference modular support functions in non-modular code. Overall there was roughly 5k lines of dead code in the kernel due to this. So far we've fixed several areas, like tty, x86, net, ... and we continue to work on
