Yes, thanks for the note (note that this branch was based on 
mm-unstable, not linux-next directly), I spotted that yesterday as well 
and got my builds going again. I think it's fixed in mm-unstable today 
as well.

It's weird that the build bot sometimes only sends stuff related to my 
WIP github branches to only me, but sometimes it decides to CC the MM 
mailing list.

Anyhow, that ahead-of-submit buildbot runs on my branches is absolutely 
fantastic, independent of who else gets CCed. (I still do cross-compiles 
for weird architectures, but at least this way I get fast feedback for 
the more common architectures)
