Hi Daniel,

there's a build-time dependency on patch 4 in both patches 5 and 6. Do
you want to pick up patches 2-5 from this series and I pick up patch 1
and hold off on applying patch 6 until after the merge window? We could
also do a shared branch, but it may not be worth the extra hassle.

Thanks,
Thierry
