The subject line does not necessarily encompass both patches of this

Change log v1->v2:
-----------------
* Both of these patches were rebased on Alex's linux-vfio-next tree taken
   from https://github.com/awilliam/linux-vfio.git.
* Replaced kvm_s390_module_hook structure with a function pointer to the
   interception handler for the PQAP(AQIC) instruction.
