I skimmed over most of the series, and I am not convinced that this is 
actually a cleanup. If we cannot really always differentiate between 
sw/hw clearing, why have separate primitives that give one the illusion 
that it could be done and that they are two different concepts?

Maybe there are other opinions, but at least for me this made the code 
harder to grasp.

I do appreciate a doc update, though :)
