This patch is not at the right place - the last few patches of the
series won't build without it.
Besides you have sent it separately before this series, so just mention
it as a dependency in the cover letter, so reviewers can pick it up
before applying the series and not witness it breaking in the course of
reviewing it. The cover letter already mentions the bitfield series as a
dependency, so the same could have been done for this one.
