To follow up on the IRC discussion we had yesterday leading to this patch
set, I had another idea of how to handle the same: Since the decompressor
code is actually fairly separate from the kernel, we could also build
multiple versions of it, and link in the same compressed vmlinux.

We already allow building Image/zImage/uImage from the same vmlinux,
and that could theoretically be extended.

Your approach of course also sounds ok, and we could eventually combine
the two.
