tick: cleanups (Shouldn't change code behavior)

As suggested by you (https://lkml.org/lkml/2014/4/14/797), this is the second lot of changes I have. I have divided the earlier patchset into three parts:
- Bugfixes, already merged
- Code cleanups which shouldn't have any functional change
- Code cleanups which may have any functional change

This patchset is targeting the second part now. Its just about moving the code around to make it more readable and obvious. Not removing any code at all, that will be addressed in next series.

V1->V2: Actually V1 was never reviewed and so it is mostly a resend of V1. Some rearrangement of patches is done though.
