XenServer can replicate this problem on all APICV capable hardware we
own, and observe the problem being fixed in all cases using v5 of the
patch from this series.

There are some unrelated issues in the heterogeneous pooling case which
cause problems, but any two homogeneous systems, one with APICV enabled
and one with APICV disabled will reliably demonstrate the issue.
