Thanks for letting me know, but I think this was fixed by the 3 earlier
patches Rusty already applied in it its tree.  I can reproduce this on

  ae46885 ("modpost: handle -ffunction-sections")

But it's fine on top of Rusty's modules-next (464f362).

Let me know if I'm missing something!

Thanks,
Quentin
