The CPU seems to mask a few bits in the offset when running
under HP-UX. ISR/IOR register contents for an address in
the processor HPA (0xfffffffffffa0000) on my C8000 and J6750:
running on Linux: 000000003fffffff c0000000fffa0500
running on HP-UX: 00000000301fffff c0000000fffa0500
I haven't found how this is switched (guess some diag in the
firmware), but linux + seabios seems to handle that as well,
so lets mask out the additional bits.
