Once the patch has passed review (hopefully by yinghai, who reviews
very well) I'd ask you to include it in the s390 tree which actually
Patch 2/3 would benefit from a more complete changelog. Why does s390
need CONFIG_ARCH_MEMBLOCK_NOMAP? How is it used and how does it work?
Do we expect other architectures to use it? If so, how? etcetera.
btw, you have a "#ifdef ARCH_MEMBLOCK_NOMAP" in there which should be
CONFIG_ARCH_MEMBLOCK_NOMAP. I don't see how the code could have
compiled as-is - __next_mapped_mem_range() will be omitted?
