I submitted the same patch a while ago, see
<http://lists.ozlabs.org/pipermail/linuxppc-dev/2009-May/072582.html>
and
<http://lists.ozlabs.org/pipermail/linuxppc-dev/2009-June/073065.html>,
maybe you can add a tested/revied for it?
If it is a problem with *byte* accesses, you might want to have a look
at
<http://lists.ozlabs.org/pipermail/linuxppc-dev/2009-June/072903.html>.
Best, Albrecht.
