Modified Files:
        syssrc/sys/arch/sun2/sun2: mem.c

Log Message:
Since physical memory below 0x2000 isn't mapped anywhere
for now, return EFAULT when /dev/mem tries to read it.
Other physical memory not managed by the pmap system is
mapped at the same virtual addresses.  Now that we
understand how VME PTEs are constructed, give mmapping
a VME bus a better chance of working..
