Message

This patch series extends the crypto adapter pass-through support to 
provide safeguards against inadvertent sharing of AP resources between
guests and/or the host, and to implement more of the s390 AP
architecture related to provisioning and dynamic configuration of
AP resources.

Tony Krowiak (7):
  s390: zcrypt: driver callback to indicate resource in use
  s390: vfio-ap: implement in-use callback for vfio_ap driver
  s390: vfio-ap: allow assignment of unavailable AP resources to mdev
    device
  s390: vfio-ap: allow hot plug/unplug of AP resources using mdev device
  s390: vfio-ap: wait for queue empty on queue reset
  s390: vfio-ap: handle dynamic config/deconfig of AP adapter
  s390: vfio-ap: update documentation
