Please have prototypes for arch_memremap and arch_memunmap in
linux/io.h so that we enforce common prototypes. This also
forces arch_memunmap to be out of line which makes sense for such
a slow patch API.
Also while you're at it please convert the ioremap_cached implementations
on metag and unicore32 which looks like misspellings, fix up the comment
in arch/arm/mm/mmu.c and the documentation in Documentation/x86/pat.txt
to not longer refer to ioremap_cache.
