Subject: [PATCH 0/3] s390/vfio-ap: queue_configuration sysfs attribute for mdevctl automation

Mdevctl requires a way to atomically query and atomically update a vfio-ap
mdev's current state. This patch set creates the queue_configuration sysfs
attribute.  This new attribute allows reading and writing an mdev's entire
state in one go. If a newly written state is invalid for any reason the entire
state is rejected and the target mdev remains unchanged.

Jason J. Herne (3):
  s390/ap: Externalize AP bus specific bitmap reading function
  s390/vfio-ap: Add sysfs attr, queue_configuration, to export mdev
    state
  s390/vfio-ap: Add write support to sysfs attr ap_config
