        syssrc/sys/arch/sh5/include: trap.h
        syssrc/sys/arch/sh5/sh5: exception.S trap.c

Log Message:
Deal with NMIs by jumping through the normal trap() code path.
At the very least, this will dump the machine state. At best,
we get into ddb().

This provides a useful way to regain control using an NMI button
if the cpu decides to spin at a high ipl.
