Pull up following revision(s) (requested by martin in ticket #532):
        sys/arch/vax/vax/machdep.c: revision 1.189
Kernel crash dumps are not properly implemented - so do not pretend they
would exist and set dumplo to 0 if dumpsize is 0. This makes savecore
happy.
XXX - implement real dumps, most of the needed code seems to be in place
already.
