Hmm, before this patch the PVR definitions were sorted in ascending
numerical order, at least for the list of 64 bit processors. Your
patch breaks this, which is not a good idea IMHO.
For example, the 970* processors are already interspersed with other
processors to maintain numerical order, therefore I don't see why the
POWER7P could not be between 970GX and BE.
Another inconsistency is that all other "plus" variants seem to
use a lower case "p" suffix. So it would be better to use POWER7p.

Gabriel
