This looks good, but just remove the whole silly "xyz_op_return()" set
too. Don't even try to fix it up.
As far as I can tell, there are just a couple of users of that
horrible interface, it really isn't worth it. Just remove it and
opencode it. They are actually broken on x86 ('xadd' only exists if
CONFIG_X86_XADD is on - i386 didn't have it), and while most people
probably don't care (i386? What's that?), I note that the x86
add_return stuff doesn't take that into account.
If somebody cares about the end result of the add that much, they can
damn well just do it themselves.
