SubjectRe: [PATCH] asm-generic: fix local_add_unless macro

Can I have a look at the offending calling code and the build failure
output ? We might consider changing these for static inlines instead.
And clearly, just changing a single primitive is not going to work. We
need to address the other similar in the same file at the very least.
