No. We don't break ioremap. We try to fallback on UC_MINUS here. But, there is something wrong happening in that path, that is resulting in this issue. I am looking at that right now. I have found another problem with this particular patch, on one of test systems. So, let us keep the revert until I fix what looks like two different problems here.
