arch/s390/kernel/topology.c:591:3: warning: 'strncpy' output truncated
before terminating nul copying 2 bytes from a string of the same length
[-Wstringop-truncation]
   strncpy(buf, topology_is_enabled() ? "1\n" : "0\n", ARRAY_SIZE(buf));

arch/s390/appldata/appldata_base.c:326:3: warning: 'strncpy' output truncated
before terminating nul copying 2 bytes from a string of the same length
[-Wstringop-truncation]
   strncpy(buf, ops->active ? "1\n" : "0\n", ARRAY_SIZE(buf));

arch/s390/appldata/appldata_base.c:217:3: warning: 'strncpy' output truncated
before terminating nul copying 2 bytes from a string of the same length
[-Wstringop-truncation]
   strncpy(buf, appldata_timer_active ? "1\n" : "0\n", ARRAY_SIZE(buf));

To avoid the warning, just reuse memcpy.
