tl dr: I don't care very deeply

I think s390 users care a lot about debugability and are less concerned
about log size. As you said, many other modules (on s390) have these
'hello' messages, so I kind of expected the ism module to show up as well.
But if you want to reject it, we can live without it ;-)
