Since there is no interception for load control and load psw instruction in the protected mode, we need a new way to get notified whenever we can inject an IRQ right after the guest has just enabled the possibility for receiving them. The new interception codes solve that problem by providing a notification for changes to IRQ enablement relevant bits in CRs 0, 6 and 14, as well a the machine check mask bit in the PSW. No special handling is needed for these interception codes, the KVM pre-run code will consult all necessary CRs and PSW bits and inject IRQs the guest is enabled for.
