My mistake.

Yes there is a second one but I did not want to send it becuase it is about
generalizing buildtar to build 3 type of tarballs: the linux binaries to be
placed in /boot, the header files for user-space, and the development headers
and tools for out-of-tree modules (this patch).

The second one makes sense, only if this one makes sense. That's why I wrote few
lines in the RFC cover letter. I should have used the format-patch option to not
enumerate patches :)
