RE: dcbz works on 862 everywhere!

For a long time, we "solved" these problems on 8xx by not properly
implementing copy-on-write pages and always marking pages dirty.
It reduced the likelyhood of the problem, reduced the MMU overhead,
but cost lots more in memory and processing time during forks.
This still may not be a bad configuration option for selected
applications.

Is it easy to patch/hard code? I would like to test the stability of my system.

I am still intrested in trying copy-on-write but I can't figure out
how. Is it a big job? Any pointers?
