KVM: s390: implement the RI support of guest
This patch adds runtime instrumentation support for KVM guest. We need to
setup a save area for the runtime instrumentation-controls control block(RICCB)
and implement the necessary interfaces to live migrate the guest settings.
We setup the sie control block in a way, that the runtime
instrumentation instructions of a guest are handled by hardware.
We also add a capability KVM_CAP_S390_RI to make this feature opt-in as
it needs migration support.
