Ugh, the fix landed in another patch :-(
updated patch below.

Daniel recently spotted that __GFP_ZERO is not (and has never been)
part of GFP_LEVEL_MASK. I could not find a reason for this in the
original patch: 3977971c7f09ce08ed1b8d7a67b2098eb732e4cd in the -bk
tree.
This of course is in stark contradiction with the comment accompanying
GFP_LEVEL_MASK.
