 Modified Files:
 	src/sys/arch/landisk/landisk: machdep.c
 Log Message:
 PR 51724 - landisk fails to reboot.
 machine_reset() - instead of trying to cause an invalid data access
 that gcc will optimize away, just use "trapa" instruction.
 G/c assignment to EXPEVT, it will be set by the actual reset.  That
 assignment has been probably cargo-culted from cpu_reset() that
 manually jumps to 0xa0000000 (the reset address) instead of triggering
 a reset.
 TODO: This code should be SuperH generic cpu_reset().
