From 71db35d26dbacd3d165522022ecb757ddc1529ea Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Fri, 10 Jul 2015 15:27:20 +0200 Subject: KVM: s390: VCPU_EVENT cleanup for prefix changes SPX (SET PREFIX) and SIGP (Set prefix) can change the prefix register of a CPU. As sigp set prefix may be handled in user space (KVM_CAP_S390_USER_SIGP), we would not log the changes triggered via SIGP in that case. Let's have just one VCPU_EVENT at the central location that tracks prefix changes.
