 See pgprot_noncached() in drivers/char/mem.c and how that's used for
mmap()ping /dev/mem.  Note that pgprot_noncached() should probably moved
to include/asm/pgtable.h as the comment suggests, so you'd better move the
relevant (MIPS) part there instead of duplicating the code.  This is
already done for ia64.
