ok - thanks. I'll take a look.

But I can tell you now that very little of the code between
x86 and parisc is shared in this area. I doubt it's as helpful
as you might think.

Yes. parisc didn't have a concept of physical CPU ID until
PAT PDC (eg A500, N-class, etc). When we want to support
CPU addition and removal, we can add physical/logical
mappings and it will no longer be 1:1.
