I've double checked this. All processors considered 7450 in the kernel 
are covered by MPC7450 RISC Microprocessor Family Reference Manual 
where hardware cache flushing procedure is described.

Nice.  Now all that remains to be done is for the patch to
be tested on actual hardware for at least a few of those
other CPUs.  Any volunteers?

I just booted & played around on a prpmc2800e (7447A, 512MB) with
this patch and it seemed to work fine.

I *may* have some old sandpoint 745x modules that still work but
I'll have to get the sandpoint working in arch/powerpc again.
I'll try to get to that in a week or so.
