Bug Description

Hello,

Few months ago I found a bug in linux kernel (kvm subsystem). This bug causes a KVM guest crush with error code 31.
I reported that bug to <email address hidden> and got following replay: http://www.spinics.net/lists/kvm/msg119265.html

Is there a chance to apply the patch fixing KVM bug to linux-lts-utopic, linux-lts-vivid?
Now that patch is already in 4.3 kernel and proposed for 3.14, 4.1 and 4.2 kernel trees.
