You probably also need something similar to http://git.infradead.org/

(note: only build-tested, not run-tested).

See http://patchwork.ozlabs.org/patch/57379/ submitted yesterday.

Yeah saw that right after I hit "send" :-)  Either it's way more
complete than what I did, or way more complex because we still
don't link with libgcc :-P

Actually, the 64bit versions of the routines are supplied by the linker,
so the vmlinux links fine.  But for modules, the final link is actually
done by the kernel module loader, thus we need to provide those routines
in this case.  linking against libgcc would not have helped.
