No, and the code paths are quite orthogonal. While today it's impossible =
to build a kernel that can drive e500v2 and e500mc systems, it might be =
possible one day. That still doesn't buy us KVM compatibility between =
the two though. And vice versa. We could improve the KVM code to =
actually be versatile between the two platforms, but then you still =
couldn't run the same kernel on both ;).
