Hi! If we are going to complain about coding style... this should really be split, one change per patch.

Default register values; are they related to the rest?

This should have no functional impact, its just a clenaup, probably
should go separately.

This is the core change, AFAICT.

Code is moved, probably should go in separately. We'll have less fun
bisecting problems when things are separate...
