Incidentally, I don't think we should have ioremap64 or
ioremap_native, instead ioremap should just take a phys_addr_t.  It
will have to do some handling of truncated addresses from pci drivers
but that should be manageable and the interface will be much more
uniform if we use ioremap everywhere instead of using ioremap,
ioremap64 and ioremap_native in different places.
