Hi Stephen,

Your conflict resolution in

8fe7fba50596 "Merge branch 'akpm-current/current'"

for mm/memory.c looks a bit off.  I get flooded with these messages:

  BUG: non-zero nr_pmds on freeing mm: 4

and fixed it with:


diff --git a/mm/memory.c b/mm/memory.c
index 450e4952c5ef..802adda2b0b6 100644
--- a/mm/memory.c
