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.

This seems to look sane in general. However, before I merge this:

- This needs to wait for a proper headers sync, which can only be done
   after the Linux code hits upstream. Shouldn't be long, I guess (I can
   queue on a staging branch while waiting.)
- As I don't have the hardware, I cannot run more than some generic
   "verify it does not break anything" testing. So, I'd like to see a
   Tested-by by someone who actually does have access to the hardware.
- I'd like to see some more review/acks from others. If other (minor)
   things crop up, I'd prefer a respin (I don't want to juggle too many
   "minor changes"...)

I am planning on a v10 series to address issues raised by Thomas, David
and you.
