David, are you planning a v2 of this soon? If so I'll hold off review until
then, if not I can get stuck in when I have time?

There will probably be a v1 called "mm: vm_normal_page*()" where I dropthe problematic bit, and respin the problematic bit as a new RFC once Ihave a better understanding.


So, no need to review right now.
