I think cbce7900598c just slightly changes the io_base value, but
it's still referring to a bus address, not a cpu address, both before
and after the patch.
0021d22b73d6 hower seems to remove the correct 'pp->io_base = range.cpu_addr;'
and replaces it with 'pp->io_base = pp->io->start;', so it's now in
the wrong address space.
