I don't really know, and honestly, don't care to spend the time and
energy to dig through to find this out.  The lzo ones jumped out at me
as I know the history behind them, and if you note, _I_ even didn't put
them in a stable kernel yet, as they have not shown up in a release from
Linus.

As the maintainer involved didn't ask you to go against the well-known
stable tree rules, that's a warning to others that perhaps something is
wrong here...
