revert but that can be done later after all other bugs have been
fixed.

Hey Linus,
We are trying out a new git flow where both me and Stefano are going
to use one git tree. Not sure yet how we are going to figure out
the branch names (discussing that now) but in the meantime here is a
git pull from that tree and also using git request pull to construct
this writeup.
