Coming up with a function name and actually implementing it are two
very different things......ioremap() should do the right thing.
There are also many other issues associated with the macros
bus_to_virt() and virt_to_bus() that are challenging.

Yes I am sure. Bursting data over the bus is hell of a lot faster,
especially in this case where the PCI bridge can combine these into
a PCI burst transfer as well.
