This is a PowerPC architecture definition. It isn't unique to the MPC8xx,
as I am obviously using a 7400 with Altivec here.

Having the common page fault handler is a good thing, we just have
to make sure we extract the information properly from the appropriate
register.

I thought there was more (than none :-) development happening with
Altivec on PowerPC Linux.  Maybe tiny test applications will work,
but my MPEG-2 decoder won't.

I'm just adding one instruction to the Instruction Exception handler
to mask the bit, so I will just check it in.
