That's not technically possible.
PARISC firmware uses the HPA to reference specific devices (including CPU).
We can use the same CPU number as PAT PDC and call them "physical".
But systems which don't have PAT PDC can only use arbitrary numbers
assigned by the parisc-linux startup code. Maybe there is a way to
make the numbers match PIM info output but I'm not sure how.
