David,

Are you going to take this to your tree or would you rather it goes via 
Xen tree?

And the same question for

https://lists.xenproject.org/archives/html/xen-devel/2017-02/msg00625.html

and

https://lists.xenproject.org/archives/html/xen-devel/2017-02/msg00754.html


(And while I am at it, I took

https://lists.xenproject.org/archives/html/xen-devel/2017-01/msg00833.html

to Xen tree, hope you don't mind)
