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).
