From 7cbde76b3d55ee299568eb943854c425b015b30c Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Tue, 21 Jul 2015 12:44:57 +0200 Subject: [PATCH] KVM: s390: adapt debug entries for instruction handling Use the default log level 3 for state changing and/or seldom events, use 4 for others. Also change some numbers from %x to %d and vice versa to match documentation. If hex, let's prepend the numbers with 0x.
