This patch prepares thp migration's core code. These code will be open when
unmap_and_move() stops unconditionally splitting thp and get_new_page() starts
to allocate destination thps.

this description is underdocumented to say the least. Could you
provide a high level documentation here please?

Yes, I'll do.

And maybe some update on Documentation/vm/page_migration will be wanted,
so will do it too.

Thanks,
Naoya Horiguchi
