looking back at what I sent Greg this was probably my fault. When taking
Kishon's patches (in particular $SUBJECT) I removed some of arch/arm/
code and ended up forgetting to add the include file which introduces
has_mailbox.

This means that my lack of attention has introduced a compile break on
Greg's tree. Oh well, s**t happens. In any case, the user is already in
Greg's tree and there's no way Greg will rebase his tree to amend
$SUBJECT there, so it will have to go separately.

I didn't even notice this before because I had the diff in my tree, just
forgot to git add and/or git reset. Too late now
