Currenty the ext_param field only distinguishes between "config change" and "vring interrupt". We can do a lot more with it though, so let's enable a full byte of possible values and constants to #defines while at it.

As promised to Andrew, and with much thanks to Andi Kleen for feedback, this is the new series of lguest patches. Main change is the move to drivers/lguest (for future non-i386 expansion), but lots of cleanups driven by Andi's feedback and the documentation effort (which made me examine every line of code). It's not perfect, but it's definitely useful. Cheers, Rusty. List of
