This really is too ugly.

I think we should fix this in sparse, not in the kernel.

There is no reason for "is this a signed type" to be that complicated,
and add that kind of nasty code in a header that is this fundamental
to the kernel and gets included in every single file that gets
compiled.

Basic rule: sparse should never make the kernel worse.
