Johannes, this looks like the thp migration memcg hookery gone bad,
could you have a look at this?

Meanwhile, Zhouping Liu, could you please not apply the last
patch:

   [PATCH] sched, numa, mm: Add memcg support to do_huge_pmd_numa_page()

and see whether it boots/works without that?

Ok, I  reverted the 31st patch, will provide the results here after I 
finish testing.

Thanks,
Zhouping
