From 71dd7e69b30dc5024a8d891e7011173a81fe7a72 Mon Sep 17 00:00:00 2001 From: David Hildenbrand Date: Tue, 30 Sep 2014 10:57:32 +0200 Subject: s390x/kvm: synchronize the cpu state after SIGP (INITIAL) CPU RESET We need to synchronize registers after a reset has been performed. The current code does that in qemu_system_reset(), load_normal_reset() and modified_clear_reset() for all vcpus. After SIGP (INITIAL) CPU RESET, this needs to be done for the targeted vcpu as well, so let's call cpu_synchronize_post_reset() in the respective handlers.
