No one has yet to submit a patch which implements the proper way to
interrupt the slave CPUs and get them to call the kgdb_nmicallback(), as
well as to run the kgdb test suite on the SMP device.

I do not have any SMP ARM hw to test this, or I probably would have
implemented myself.

If you come up with any patches you can submit them here and please cc
kgdb-bugreport at lists.sourceforge.net.  If you have questions about the
kgdb test suite I am sure we can find some answers.

Thanks,
Jason.
