From b7e6e4d3602c738b8f61225d9f4514945df52f07 Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Thu, 22 Jan 2009 10:29:08 +0100 Subject: [PATCH] KVM: s390: Fix SIGP set prefix ioctl This patch fixes the SET PREFIX interrupt if triggered by userspace. Until now, it was not necessary, but life migration will need it. In addition, it helped me creating SMP support for my kvm_crashme tool (lets kvm execute random guest memory content).
