I think the underlying problem was pointed out before: The page table
accessor functions can't currently propagate errors, and hence
ioremap() can't be forced to fail if Xen refused a mapping. And then, as
I wrote in an earlier reply, the check for not trying to map RAM from
ioremap() is pretty pointless (and hence no help) currently for the Xen
case.
