If it's a GPL violation to ship the non-GPL'd firmware in the source
tarball, it's also a GPL violation to distribute it as part of a
vmlinux.

So yes, putting it in a separate source tarball removes the GPL worries
there -- but if you're then going to use the CONFIG_BUILTIN_FIRMWARE
feature and build non-GPL'd firmware into your vmlinux, that brings
exactlly those same worries right back again.

If you build non-GPL'd firmware into your kernel, you may not distribute
that kernel image (although currently we do just that; we shouldn't).

Fedora already uses 'doctored' tarballs for stuff like openssh; I think
it would be reasonable enough to do that with a firmware-less kernel
source tarball too. It's easy enough to build the firmware package
separately (although first, I'm going to make the kernel srpm spit out a
'kernel-firmware' subpackage; we can talk about splitting it later).

That's nothing special -- it's just the same as we should always be
vigilant for someone slipping non-GPL'd _code_ into the kernel.
Should we just give up, just because people slip up occasionally?
