Damaged as the patch is, I was able to apply it by using
'patch -l' (ignore whitespace) + some fuzz. Not something that
Linus or Andrew would or should do.
I built and booted the kernel, it's running fine (x86_32 notebook).

This is in the General setup menu. How about putting it into the
EMBEDDED menu instead? [Configure standard kernel features (for

There are still several build warnings that need attention:
