Commit Message

Tony Krowiak June 29, 2018, 10:47 p.m. UTC 
Updates the linux header files in preparation for introduction
of the VFIO AP device:

* Added a feature ID to indicate AP facilities are installed

* Added a device attribute to the KVM_S390_VM_CRYPTO group to
  indicate whether AP instructions are to be interpreted

* Added VFIO device information for AP devices
