Comment 18 for bug 2056706

The fix worked for our Xen virtual machines, and I assume the fix needs to be done on all those platforms, because https://bugzilla.kernel.org/show_bug.cgi?id=218654 fixes an actual bug in a Xen driver. There's even talk in the bug about making a CVE.

But, I have no way to explicitly confirm those other kernels, but I'm inclined to change the tags to 'verification-done' to avoid a automated rollback.
