We are still at girdlock here because linux-sh mailing list seems be /dev/null,
while email to Paul Mundt kept bouncing.

I tried to contact someone in SuperH community, via the superH Linux portal - and

Unfortunately Paul Mundt is no longer work for Renesas and SuperH Linux.
Maybe he intentionally shutdown his e-mail server. So this is not a simple
server problem.  Very sorry for your inconvenience.

them plus this is a straight forward mechanical change.
