Yep, I've tested his stack as well (just got some results and it seems
ok).

I've got all three of my patches rebased. I'll repost them shortly, am
just trying to verify they still work as expected on NUMA, NUMA w/
memoryless and non-NUMA, as before.

FWIW, you just need to

sed -i 's/node_memory_map/node_states(N_MEMORY)/g' mm/hugetlb.c

these two apply cleanly. Everything should build at that point, as well.

I'll make sure you're on the Cc once I repost.
