I think this question is more towards ppc folks,
since both Daniel and myself said before that it looks ok.
Philippe just tested the previous version of this patch on ppc64le...
I'm guessing that Matt (original author of bpf jit for ppc) is not replying,
because he has no objections.
Either way the addition is tiny and contained, so can go in now.
