As Avi noted recently, there is a problem in way we inject interrupts into the userspace APIC under KVM: The TRP check over the iothread may race with the VCPU raising the TPR value while in KVM mode. Patch 3 addresses this issue.
The other two patches fix problems I came across while thinking about the first one. Who would like to process this series, up/master? Or should it go in directly?
