nit: I'm not sure the placement of this comment really makes sense after the change. You have added supported  for AIX aliases (i.e. pwr7)  above this comment, so it's not clear why we're grouping the comment to only the CPUs below. (Maybe best to leave the comment where it was, and not try to split this into two lists)
