(add) consolidate io_remap_pfn_range() so that different arches don't use different parameters for io_remap_page_range();
io_remap_pfn_range(): add io_remap_pfn_range() for all arches; eliminate the <iospace> parameter from sparc/sparc64; add MK_IOSPACE_PFN(), GET_IOSPACE(), and GET_PFN() for all arches but primarily for sparc32/64's extended IO space, sparc: kill the hack of using low bit of <offset> to mean write_combine or set side-effect (_PAGE_E) bit; future: convert remaining callers of io_remap_page_range() to io_remap_pfn_range() and deprecate io_remap_page_range();
BTW, built successfully on 8 arches, but needs testing on sparc32/64, which I can't do.....
