[PATCH v5 0/6] kvm: Make ioeventfd usable on s390.

[Cornelia Huck <cornelia.huck@de.ibm.com>]

v5 of the ioeventfd patch set, this time with a proper return code
from __diag_virtio_hypercall(), otherwise unchanged.

v4 -> v5:
- Proper return code in __diag_virtio_hypercall()
v3 -> v4:
- Pass cookies in virtio-ccw notify hypercall
- Coding style
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: s390: Export virtio-ccw api.
  KVM: Initialize irqfd from kvm_init().
  KVM: Introduce KVM_VIRTIO_CCW_NOTIFY_BUS.
  KVM: ioeventfd for virtio-ccw devices.
  KVM: s390: Wire up ioeventfd.
