This is the same as the asm-generic version (better actually, because it
doesn't use macros). Just use the existing code here, and maybe add
a patch to fix that one to use an inline function as well ;-)

Hmm, I missed that file in my asm-generic series. Your code is 90% shared
with mips, parisc, sh, sparc and um, so it seems like I should put it
on my TODO list for generalization.
