OK, so this is flags & GFP_SLAB_BUG_MASK BUG_ON because gfp is
___GFP_HIGHMEM. It is my [1] patch which has introduced it.
I think we need the following. Andrew could you fold it into
mm-memcg-use-consistent-gfp-flags-during-readahead.patch or maybe keep
it as a separate patch?

Thanks for the report Sergey!
