Keir:
        The latest patch is doing smp_call_function() at time of
arch_vmx_do_resume :-)
        But I get another issue recently that need it to be done
earlier. In VMX domain save/restore case, it pauses the VMX domain and
then do states save (and destroy). In this case the arch_vmx_do_resume
is not invoked, so it looks like doing smp_call_function earlier has
other benefits, any suggestion?
thx,eddie
