Looks fine now, thanks.

True, but our core support lives in arch/.  The same is true for PHB
code etc.; if Altix messed this up, that doesn't mean we need to :-)

This would naturally fall out as a separate patch then, as well.

Maybe msi-pseries then?  Oh wait, they changed that name too ;-)

If you move this code to arch/powerpc/platforms/pseries/, you could
just call it "msi.c".  I don't like the msi-rtas name -- but, I don't
feel that strongly about it, just a suggestion.
