Obviously impossible cpus shouldn't ever be running, but stranger things have happened. So be paranoid and initialise data_offset with a poison value in case we don't set it up later. Based on a patch from Anton Blanchard. Signed-off-by: Michael Ellerman Signed-off-by: Benjamin Herrenschmidt --- Reading git-diff-tree failed
