ALPHA_FS finally compiles again
SConscript:
Use a couple more FS sources, still don't compile that much
arch/alpha/faults.hh:
the unimp fault should probably exist in nonfs too.
dev/alpha_console.cc:
dev/alpha_console.hh:
dev/simconsole.cc:

dev/uart8250.cc:
dev/uart8250.hh:
sim/process.cc:
sim/system.cc:
fixes for newmem
dev/io_device.hh:
a system pointer is probably useful for every device to have
mem/bus.hh:
mem/physical.cc:
new address ranges function
python/m5/objects/SimpleDisk.py:
simple disk now has a system pointer rather than physmem directly
