http://marc.info/?l=linux-mm&m=129842655126639&w=2

Per developer:

"patch 1 I for sure. The rest I'm unsure yet. I'm unconvinced following
prev page is better than vma (definitely it was wrong for KSM and in
fact Andi dropped that patch already). Anyway Andi knows NUMA
best. We'll see. Last patch I'm unsure if we can include it until it's
upstream because it becomes API visible.

In some ways we've the same problem with the smaps new line, we've to
wait it to hit mainline before showing the smaps, but that's a minor
issue, and we already showed the anonpages in /proc/meminfo (it got
merged upstream so no problem, but usually apps shouldn't break
because of a newline)."
