Currently this command uses the monitor cpu (which can be set by the user) as the cpu for whose registers will be dumped. Sometimes it is useful to see the registers for all cpus and currently this requires setting the monitor cpu and the re-running the command for each cpu in the system. I would be nice if there was an easier way to do this. Add the "-a" option to the info registers command to dump the register values for all cpus.
