The s390 dump mechanisms cannot be switched to memblock (from using something s390 specific called memory_chunk) without the nomap list. I'm also working on another enhancement on s390 that will rely on a clean transition to memblock. I have written and tested the stuff on top of our local development tree. And then realised that it does not fit the linux-next tree. So I converted it to fit linux-next and posted it. Have to maintain two versions now.
