None, at the moment. My work is trying to add iomem support to scatter
lists and thus I want to call ioremap in scatterlist.c. That's when
things fail to build. We could put an '#ifdef HAS_IOMEM' around only the
uses, but I thought this approach was cleaner. However, if people would
rather I do that, let me know and I will.

This doesn't really work when we try to use it in a core library which
can't depend on HAS_IOMEM.

Thanks,
