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.
