I have been doing some work on kgdb to pull a few of it "fingers" out of
various places in the kernel. This is the final location where we have
a kgdb intercept not covered by a notify.
I like the idea, but the hook should be in die_nmi(), not in the
watchdog, using the reason that is already passed into die_nmi.
die_nmi() is also called for a real NMI.
Hmm.. just looked at traps.c. Seems die_nmi is NOT called from the nmi
trap, only from the watchdog. Also, there is a notify in the path to
the other nmi stuff.
