This turned out to be something fundamental in types.h.
My fix is appended.

I will do a proper submission to davem later as part of
a few other trivial fixes.

Subject: [PATCH] sparc: use asm-generic version of types.h

This fixes build errors in samples/

We failed to include the header file that define __u16 because __sparc__
was not defined.
This check is not required - and removing this made us
compatible with the generic types.h version. So use that.
