It is needed for s390 bootmem -> memblock transition. 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.
