KVM performs TPR raising asynchronously to QEMU, specifically outside QEMU's global lock. When an interrupt is injected into the APIC and TPR is checked to decide if this can be delivered, a stale TPR value may be used, causing spurious interrupts in the end. Fix this by deferring apic_update_irq to the context of the target VCPU. We introduce a new interrupt flag for this, CPU_INTERRUPT_POLL. When it is set, the VCPU calls apic_poll_irq before checking for further pending interrupts. To avoid special-casing KVM, we also implement this logic for TCG mode.
