From 4e0b1ab72b8af961bcaca9ec1475279c1cd9579c Mon Sep 17 00:00:00 2001 From: Fan Zhang Date: Tue, 29 Nov 2016 07:17:55 +0100 Subject: KVM: s390: gs support for kvm guests This patch adds guarded storage support for KVM guest. We need to setup the necessary control blocks, the kvm_run structure for the new registers, the necessary wrappers for VSIE, as well as the machine check save areas. GS is enabled lazily and the register saving and reloading is done in KVM code. As this feature adds new content for migration, we provide a new capability for enablement (KVM_CAP_S390_GS).
