Won't it be cleaner to just move this into arch_domain and avoid a
bunch of the ifdefary? As the initialization of the fields would be
moved to arch_domain_create() also.
Maybe we would want to introduce some kind of arch-specific event
channel handler so that the bind PIRQ hypercall could be handled
there?
Thanks, Roger.
