I just noticed this. "git merge" wont work.

We had our metldown changes in before the sync to 4.1.49 so the order is
off. You will need to cherry-pick.


I doubled checked via:

git checkout standard/base
git fetch 
https://github.com/MontaVista-OpenSourceTechnology/linux-nonlts-secfix
linux-4.1.y-lts
git cherry-pick 07369b8
git cherry-pick 07369b8..ee7eeb3

sorry for making things more complicated.
