Hi Mel,

I tried giving it a spin, but it won't apply at all on the latest -mm
tree:

$ git am -3 numa/*
Applying: mm: numa: Do not dereference pmd outside of the lock during NUMA hinting fault
Applying: mm: Add p[te|md] protnone helpers for use by NUMA balancing
Applying: mm: Convert p[te|md]_numa users to p[te|md]_protnone_numa
fatal: sha1 information is lacking or useless (mm/huge_memory.c).
Repository lacks necessary blobs to fall back on 3-way merge.
Cannot fall back to three-way merge.

Did I miss a prerequisite?


Thanks,
Sasha
