Indeed removing irq.h header file is no more possible since commit c77dcacb397519b6ade8f08201a4a90a7f4f751e, "KVM: Move more code under CONFIG_HAVE_KVM_IRQFD" which moves among other things kvm_register_irq_ack_notifier and kvm_unregister_irq_ack_notifier in eventfd.c. including virt/kvm/ioapic.h might fix the problem but I am OoO next week and cannot investigate further right now. Please can you remove that commit. Sorry for the inconvenience.
