Now that struct _irqfd does not keep a reference to storage pointed to by the irq_routing field of struct kvm, we can move the statement that updates it out from under the irqfds.lock and put it in kvm_set_irq_routing() instead. That means we then have to take a srcu_read_lock on kvm->irq_srcu around the irqfd_update call in kvm_irqfd_assign(), since holding the kvm->irqfds.lock no longer ensures that that the routing can't change. Combined with changing kvm_irq_map_gsi() and kvm_irq_map_chip_pin() to take a struct kvm * argument instead of the pointer to the routing table, this allows us to to move all references to kvm->irq_routing into irqchip.c. That in turn allows us to move the definition of the kvm_irq_routing_table struct into irqchip.c as well.
