Given that setup.h is exported by include/uapi/asm-generic/Kbuild.asm (as part of
userspace header ABI) there's no way we can avoid it's uapi sibling - even if
empty. But to workaround patch discarding it, I will add a placeholder comment in
generated setup.h (just like you did for arch/cris). Would that take care of it ?

BTW looking at metag port, it seems that <asm/setup.h> does #include
<uapi/asm/setup.h>, but latter doesn't exist in the repository - is it generated
for you James or is this same issue which David elucidated to above ?
