From 48e9a6c1f54695609b709bf674aac133794ada00 Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Wed, 24 Sep 2014 16:37:20 +0200 Subject: 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.
