You are displaying a dangerously amateurish attitude towards quality control 
and you clealy have no idea what it takes to push fixes into -stable.

You forwarded a brand-new, visibly dangerous native kernel commit to -stable 
without Cc:-ing the maintainers and you have caused a native kernel regression 
that way. You are not maintaining the code in question and you have not 
committed the patch in question.

-stable team, please revert this commit. The whole issue obviously needs more 
testing and we'll forward a proper fix once it's available and tested.
