Subject: [PATCH 0/2] Add back capability of calling KGDB/KDB via UV NMI call.


The following two patches add the capability of calling KGDB/KDB after
receiving the NMI signal from the UV system 'power nmi' command.  This
is mainly required because the system console on UV cannot send the
break signal so when the system I/O is not working, the power nmi
command from the CMC is the only method to interrupt the system.
