Not on x86 we can't, it's not there - asm/io.h seems safest AFAICT, everyone has it and both SH and x86 include the pci_iomap.h.

Hmm, the code does include <linux/io.h>, and it includes <asm/io.h>

Yeah, at least not on SH - it is on most architectures.

I don't think arch/sh/include/asm/io.h includes the necessary thing.

I'm just about to submit a patch which makes it the (or at least a) necessary thing. This stuff shouldn't be complicated or inconsistent.
