Don't know, I haven't looked closely.  I am not planning on looking at this for
3+ weeks, as I want to sort out the KVM_CAP_MAX_VCPUS mess first[*], along with
a multitude of other bugs/flaws in the AVIC and posted interrupt code.  I have
crude patches, but they need changelogs and more testing; I don't expect to post
them for at least 2 weeks.
