I think I mostly agree, except for reverting 6060e8df5178, which I don't think would be correct. That reintroduces the possibility of flushing the I-cache twice in that path, once for aliasing vipt dcaches, and again for asid tagged vivt icaches. I'd rather have the code structured so we only do this once.
