They won't hit Linus until I send my pull request.

It's not a mess, it's a collection of patches which touch either arch/powerpc
or arch/powerpc/kvm, or are otherwise related.

Yeah I could have merged just the start of Paul's series, but that
seemed pointless, it doesn't prevent or add any conflicts, and it means
I'm unable to test his series as a whole.

Paul has also now merged the remaining two commits, and sent you a pull
request including them.

I don't see how that helps anything.

In fact it guarantees a mess because those two commits would now go to
Linus via my tree (cherry picked) and via Paul's as part of his second
merge of the topic branch.

So unless you can give me a good reason I'll merge the tip of the topic
branch into my next, as planned.
