I know which patch he is on about, it's entitled "page-allocator: Preserve
PFN ordering when __GFP_COLD is set". There are a number of patches that
I don't believe have made it upstream or into mmotm but I've lost track
of what is in flight and what isn't. When an mmotm against 2.6.31-rc2 is
out, I'll be going through it again to see what made it in and resending
patches as appropriate.
