Thanks for the patch.
I have noticed that you submitted these patch-set (together with the
other two you sent here and more) upstream and they will be in the
stable branch.
The easiest path here is also to go through the stable release of
linux-source where uml is built from. I'll keep an eye on the stable
tree but it'd be very helpful if you could add the stable tree commit
ids once the patches get included. Same story for the other two bugs.

Thanks!
