[PATCH v3 0/5] kvm: Make ioeventfd usable on s390.

Here's the latest version of my patch series enabling ioeventfds
on s390, again against kvm-next.

Patches 1 and 2 (cleaning up initialization and exporting the virtio-ccw
api) would make sense even independent of the ioeventfd enhancements.

Patches 3-5 are concerned with adding a new type of ioeventfds for
virtio-ccw notifications on s390. The naming is now hopefully clearer.
We won't add ioeventfd support for the legacy s390-virtio transport.

Please consider applying.

v2 -> v3:
- Added a patch exporting the virtio-ccw api and use it for the
diagnose implementation.
- Better naming: We're dealing with virtio-ccw notifications only.
v1 -> v2:
- Move irqfd initialization from a module init function to kvm_init,
eliminating the need for a second module for kvm/s390.
- Use kvm_io_device for s390 css devices.

Cornelia Huck (5):
KVM: Initialize irqfd from kvm_init().
KVM: s390: Export virtio-ccw api.
KVM: Introduce KVM_VIRTIO_CCW_NOTIFY_BUS.
KVM: ioeventfd for virtio-ccw devices.
KVM: s390: Wire up ioeventfd.
