From 04c2b5168e242e6fa6901442bd399aa7087effca Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Fri, 24 Jan 2014 17:18:38 +0100 Subject: s390x/kvm: Add missing SIGP CPU RESET order The SIGP order CPU RESET was still missing in the list of our supported handler. This patch now adds a simple implementation, by using the cpu_reset() function that is already available in target-s390x/cpu.c.
