(1) object code can be shared (where the hardware makes that possible), and
(2) so that the file names better describe the systems which use them. (the
pci_swiz* files are for machines whose PCI interfaces require address
"swizzling." Later, there will be probably be other sets, e.g. pci_bwx*
for machines whose chipsets can easily deal with the Alpha BWX extensions
when doing device accesses.)
