[qemu-s390x] [PATCH v3 1/7] linux-headers: linux header updates for AP s


From: Tony Krowiak
Subject: [qemu-s390x] [PATCH v3 1/7] linux-headers: linux header updates for AP support
Date: Thu, 15 Mar 2018 19:24:54 -0400

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
