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?
Jan Kiszka (3):
apic: Resolve potential endless loop around apic_update_irq
apic: Reevaluate pending interrupts on LVT_LINT0 changes
apic: Defer interrupt updates to VCPU thread
