(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.....

build failures there are not related to this patch.
