Yes, after discussion with Rusty, it appears that beefing up stop_machine_run is the right way to go. And it has benefits for non-paravirt code as well, such as allowing plug-in kprobes or oprofile extension modules to be loaded without having to deal with a debug exception or NMI during module load/unload.
