In looking at my queue, it's still in there, just haven't gotten to it yet... > The Xen warning unfortunately appeared with 58d378b24b7f ("xen/balloon: Fix > crash when ballooning on x86 32 bit PAE"), which was backported from mainline > into v4.4.10. > I made a fix that is in -next now, bdadcaf2a7c1 ("xen: remove incorrect > forward declaration"), but I don't know when that will get merged. See, I missed this getting added, not good on my part.
