As part of this, patch 1 moves feature MSR initialization to
kvm_arch_init_vcpu, which also fixes a problem related to the ordering
of kvm_put_msrs and kvm_put_nested_state.  Patch 2 adds a customizable
ucode-rev property that is supported by both TCG and HVF.  Finally patch 3
adds the KVM support, including getting the host version via KVM_GET_MSRS
and passing it back to the guest for "-cpu host" only.
