You mean you also need these two fields to hold irqs ? If in-kernel irqchip works, all irqs from userland may transfer to kernel through another path. You can reference KVM_IRQ_LINE vm ioctl for that. If you don't need these two fields as well, we can use CONFIG_X86 macro to comment out them in common code instead.
