Merge branch 'vfio-ap' into features
Tony Krowiak says:
===================
This patch series is for the changes required in the vfio_ap device
driver to facilitate pass-through of crypto devices to a secure
execution guest. In particular, it is critical that no data from the
queues passed through to the SE guest is leaked when the guest is
destroyed. There are also some new response codes returned from the
PQAP(ZAPQ) and PQAP(TAPQ) commands that have been added to the
architecture in support of pass-through of crypto devices to SE guests;
these need to be accounted for when handling the reset of queues.
