this might be due to the change in using a cache invalidate instead
of writeback/invalidate and the 128 byte linesize of the second level
cache on that R4k CPU modules. The patch below should fix that.
I have no R4400 IP22 handy, so I'd appriciate if someone could test
the patch. If it works, I'll sent the patch to Ralf with proper S-O-B.
