We add a new structure vfio_ap_queue, to hold per
queue information useful to handle interruptions.
- apqn: AP queue number (defined here)
- isc : Interrupt subclass (defined later)
- nib : notification information byte (defined later)
So, you basically simply want quick access to these? Makes sense.
The vfio_ap_queue structure is allocated when the vfio_ap_driver
is probed and added as driver data to the ap_queue device.
It is free on remove.

The structure is linked to the matrix_dev host device.
Hm, I don't quite follow?
Sorry, do not try to, this has been left from a previous internal version.
I will suppress this

Patch looks reasonable; might make sense to squash it with later
patches (still need to read).
