I need to check who uses them, but in all cases, I don't see what they do in iomap.c, it's not their place. Versions that would transparently use MMIO or PIO would make sense. A pure MMIO implementation doesn't, that has to be arch specific. It makes the generic iomap suddently non-portable in some ways. So I think we need to make sure all archs grow readsb,sw,sl etc... and just have iomap use those for the "transparent" versions.
