Hi Mina,

I don't know if this was supposed to fix the 2 build reports that I made,
but this does not apply cleanly to mmotm (and it's a reply email so it's
more difficult to apply anyway):

Applying patch mm-hugetlb-fix-CONFIG_CGROUP_HUGETLB.patch
patching file mm/hugetlb.c
Hunk #1 succeeded at 289 with fuzz 1.
Hunk #2 succeeded at 325 with fuzz 2.
Hunk #3 FAILED at 435.
1 out of 3 hunks FAILED -- rejects in file mm/hugetlb.c
