KVM: s390: device attrs to enable/disable AP interpretation
Introduces two new VM crypto device attributes (KVM_S390_VM_CRYPTO)
to enable or disable AP instruction interpretation from userspace
via the KVM_SET_DEVICE_ATTR ioctl:
* The KVM_S390_VM_CRYPTO_ENABLE_APIE attribute enables hardware
interpretation of AP instructions executed on the guest.
* The KVM_S390_VM_CRYPTO_DISABLE_APIE attribute disables hardware
interpretation of AP instructions executed on the guest. In this
case the instructions will be intercepted and pass through to
the guest.
