are available in the git repository at:
https://github.com/MontaVista-OpenSourceTechnology/linux-nonlts-secfix
linux-4.1.y-lts
I'm getting conflicts when I try and merge this into linux-yocto-4.1
standard/base
yow-bashfiel-d4 [/home/bruc...to-4.1.git]> git merge linux-4.1.y-lts
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.
No worries. Those same cherry picks were clean for me as well, so
this is now pushed.

Judging by the conflicts, it looks like the first round of Meltdown
fixes are being merged twice .. i.e. git isn't picking them up as the
same commits.
In case I'm doing something odd (I'm merging a LOT of kernel changes
today). Can you look at this and see if you see the same thing ?
