[Qemu-devel] [PATCH v2 for-2.12 06/10] s390x/tcg: Implement STORE CHANNEL PATH STATUS

[David Hildenbrand <david@redhat.com>]

Just like KVM does, we should suppress this instruction:
    When this instruction is not provided, it is
    checked for privileged operation exception and the
    instruction is suppressed by the machine
