[ This has no changes since 6d/10. None! Andi tried to make me change it, but I defended it. This one patch is unscathed. Bwaha! ] Finally, we put in the Makefile, so it will build. There's a small complexity in creating the switcher code (hypervisor.S) ready to be copied into the top of memory, but it's not too bad. Really. Stop looking at me like that, Andi. It's fine as it is.
