Stefano and I discussed this IRL. Changing how we handle HCR would
involve checking that places like gic_inject and the
XEN_DOMCTL_set_address_size handling did the right thing. In principal
its easy but it's a little too subtle for us to be comfortable in making
such a change now. So I'm going to stick with the original approach
here.
