Paolo, two fixes for s390. Turning gisa off was making us write an uninitialized value into the SIE control block due to the V!=R changes. Errors when (un)sharing SE memory which were previously unchecked are now resulting in panics since there's nothing that the guest can do to fix the situation. Please pull.
