From: Andrey Smetanin <asmetanin@xxxxxxxxxxxxx> Actually kvm_arch_irq_routing_update() should be kvm_arch_post_irq_routing_update() as it's called at the end of irq routing update. This renaming frees kvm_arch_irq_routing_update function name. kvm_arch_irq_routing_update() weak function which will be used to update mappings for arch-specific irq routing entries (in particular, the upcoming Hyper-V synthetic interrupts).
