Change the oprofile_cpu_type in cputables.c to be ppc64/970MP. Oprofile
needs to distinquish the MP from other 970 processors so it can add some
new counters specific to the 970MP

Just out of curiosity, what are those? I never saw any,
but I'd love to know :-)

They are the IBM JS21 blades

I think Segher might have had "what are the new counters" in mind when he asked that, not where the processors are used. :-)

They are different MMCRx settings for counting certain events.

Yes indeed :-)

Heh of course. I meant _which_ events, of course.
But nm, I'll look it up myself :-)
