As I said to Arnd on the 2nd May, I've dropped this patch because it was
causing too many other problems.  I'd much prefer to have a single patch
which made this change and fixed all the other places which Arnd identified
as well.  If you still want to make this change, please ensure that all
implementations and users of ioremap() are correctly updated in a single
patch and resubmit.  Thanks.
