s390/topology: call set_sched_topology early
The call to topology_init is too late for the set_sched_topology call. The initial scheduling domain structure has already been established with default topology array. Use the smp_cpus_done() call to get the s390 specific topology array registered early enough. Cc: stable@vger.kernel.org # v3.16+ Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
