Keir, you mentioned that start_info probably doesn't make much sense for PowerPC. However, if for no other reason than linux/drivers/xen has many
references to it, we'd like to fix it for now and figure out how to
replace it later.

I think that structure is quite x86-specific. I'd be happy to see direct references to start_info replaced in drivers/xen. Obvious (and ugly) low-hanging fruit is test for SIF_INITDOMAIN. Replacing with arch-specific is_initial_domain() or similar would be a great patch to receive. A couple of the others (e.g., console_mfn, store_mfn) are a bit harder -- how do you communicate those on ppc?
