On EOI, there is no need to set KVM_REQ_EVENT unconditionally. The PPR update is already setting it if resetting the ISR bit causes PPR to decrease. Even a level-triggered IOAPIC interrupt will set KVM_REQ_EVENT on a reinjection (ioapic_service -> kvm_irq_delivery_to_apic and from there to __apic_accept_irq).
