I've not been following this thread too closely..

Do you have any patches you want included into mainline?

No need to fix anything mainline

O.K. I thought there was a problem with user space using it, some
flushes missing somewhere? Or VM mapping problem? Has that been fixed?

Hmm, there was some discussion about an issue like that in this list at
end of February/beginning of March, which was resolved then. On the
other hand there is an unanswered mail from Cloudy at 20. April about a
failing kernel hash test. Maybe he can elaborate on this?

I think the problem is not in mv_cesa but in
flush_kernel_dcache_page(). I have proposed a fix here:

There was a little bit of discussion on the patch, but it has not
been picked up yet.
