BTW: The patchset seems to significantly speed up livepatch selftests
     in tools/testing/selftests/livepatch. I haven't measured it.
     But I do not longer have to switch screen and do anything else.

     The transition speed is not our priority. But it is another nice
     win of this patchset. I only hope that we did not introduce
     any race ;-)
