I've just attached this tarball to this email. It might be rejected by
the mailing list, but as you are also in the "To" field you should
receive it.

Actually the archive is the full content of arch/arm/boot/compressed
from my build directory and I removed vmlinux and all the piggy files to
have a small archive.

If they are also needed then I can provide an url for it.
