Merge remote-tracking branch 'qemu-kvm/uq/master' into staging
* qemu-kvm/uq/master:
virtio: move common irqfd handling out of virtio-pci
virtio: move common ioeventfd handling out of virtio-pci
event_notifier: add event_notifier_set_handler
memory: pass EventNotifier, not eventfd
ivshmem: wrap ivshmem_del_eventfd loops with transaction
ivshmem: use EventNotifier and memory API
event_notifier: add event_notifier_init_fd
event_notifier: remove event_notifier_test
event_notifier: add event_notifier_set
apic: Defer interrupt updates to VCPU thread
apic: Reevaluate pending interrupts on LVT_LINT0 changes
apic: Resolve potential endless loop around apic_update_irq
kvm: expose tsc deadline timer feature to guest
kvm_pv_eoi: add flag support
kvm: Don't abort on kvm_irqchip_add_msi_route()
