No, and I didn't actually make these changes, either :-)
I'm working on some 8xx debugging right now, so let's experiment
with some changes. I don't understand why other processors, especially
G2 cores like 82xx, aren't finding the same problems we are having
with 8xx. Logically, we are all doing the same thing, unless there are
some tlb invalidates on these other processors that I'm forgetting
about.
We just seem to be running into stale entries, and we have to fix it.
Thanks.
