Um, one other minor semantic issue.  The semantics of

Yes, I had thought about this.  It's not clear to me it's problematic yet.

I guess it could be, as if I understood correctly Keir's later post, we
would like to run on other subarch.

I see, you would like domain zero to support other subarchs?

I guarantee you it is not going to be voyager! There should be no issue for user domains, but could domain zero could potentially need to know things about the hardware subarch, say for some large NUMA systems?
