From 24d05ff863e78544e8538a792e3234291cdd5650 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 17 Aug 2015 08:09:17 +0200 Subject: [PATCH] s390/nmi: initialize control register 0 earlier Change machine_check_init() to an early_initcall(). This makes sure it will be called before all other cpus are online and therfore saves us a lot of pointless smp_call_function() calls. The control register settings will be forwarded to the other cpus when they will be brought online.
