Subject: Re: dcbz works on 862 everywhere!

Hi guys.
I revitalized my old test environment on a
mpc860t (XPC860TZP50B5 / 3J21M to be precise).
I found that 'dcbz' (while failing to set DAR)
indeed sets MD_EPN correctly. Hence, Jocke's fix
(copy EPN[0:19]->DAR) would handle that.
My older idea (fixing up MD_EPN and DAR based
on the faulting instruction opcode and the involved
GPR contents) should work even if we have neither
a valid MD_EPN nor DAR.
