[PATCH] ppc32: Kill PVR_440* defines
The following patch changes the usages of PVR_440* into strcmp's with the
cpu_name field, and removes the defines altogether. The Ebony portion was
briefly tested long ago. One benefit of moving from PVR-tests to string
tests in general is that not all CPUs can be on and be able to do this type
of comparison.
See http://patchwork.ozlabs.org/linuxppc/patch?id=1250 for the original
thread.
