v2: rebase on vm_size scale change. Adjust vm_size default to 8,
Better handle the default and smaller values.

Hey Alex,
can you use this version instead of the one you already have in
drm-next-3.17-wip? It depends on a change from drm-fixes-3.16, so you
need to merge (or rebase) your -next branch to apply it.
Apart from that I also have a couple of more VM changes for 3.17, but
those need a merge with the latest 3.16 fixes as well.
Thanks,
Christian.

Ok. I'll drop the patch for now. I'll send a pull with all the
additional patches that depend on fixes once Dave merges it.
