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
aves start entering.
The new argument "send_ready" was added for KGDB to signal the NMI handler
to release the slave CPUs for entry into KGDB.
