I'm adding oprofile support for 7450 (and derivative) processors, and
I'm considering adding a couple PPC_FEATURE bits (one for classic, and
one for fsl-book-e perfmon).
1) The need to distinguish between Freescale Book-E processors with
performance monitor support, Classic PPC processors with perfmon
support, and processors without perfmon support. (ie - 7450 parts will
have support, but 7410 parts will not for now).
2) Applications could determine if these features were present, and
decide between using mfspr and mfpmr instructions to read the counters
