Subject: [PATCH v2 0/2] s390/vfio-ap: do not open code locks for

The subject line does not necessarily encompass both patches of this
two-patch series, but I left it as versions 1 and 2 used this subject
line and I didn't want to confuse those who reviewed those patches.

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.

Tony Krowiak (2):
  s390/vfio-ap: r/w lock for PQAP interception handler function pointer
  s390/vfio-ap: replace open coded locks for VFIO_GROUP_NOTIFY_SET_KVM
