This patch series is the QEMU counterpart to the KVM/kernel support for 
guest dedicated crypto adapters. The KVM/kernel model is built on the 
VFIO mediated device framework and provides the infrastructure for 
granting exclusive guest access to crypto devices installed on the linux 
host. This patch series introduces a new QEMU command line option, QEMU 
object model and CPU model features to exploit the KVM/kernel model.

See the detailed specifications for AP virtualization provided by this 
patch set in docs/vfio-ap.txt for a more complete discussion of the 
design introduced by this patch series.

Note: This series implements the minimal viable product (MVP) and does not
      provide support for hot plug/unplug, migration, or VSIE. The goal
      of the MVP model is to solidify a base upon which these additional 
      features will be built.

v4 => v5 Change log:
===================
* Added MAINTAINERS entries for VFIO AP
* Added explanation for why we are only supporting zEC12 and newer CPU 
  models.
* Changed CPU model feature qci=on|off to apqci=on|off
* Misc. minor changes
