so you can restore by a command line like this:
m5.opt fs.py --checkpoint_dir="/my/ckpt/dir" -c 3
configs/example/fs.py:
add in checkpoint restoration option, you can restore a checkpoint by giving a directory, and then giving a checkpoint number, the earliest checkpoint is 1, the latest is N.

src/cpu/simple/atomic.cc:
add in serialization of AtomicSimpleCPU _status. Kev says that this will break uniform serialization across CPUs since each type of CPU has its own "status" enum set. So, the repercussions are that if you serialize in this CPU, you must first unserialize in this CPU before switching to something else you want.

1) return the periodicity of checkpoints back into the code (i.e. make m5 checkpoint n m meaningful again).
2) to do this, i had to much around with being able to repeatedly schedule and SimLoopExitEvent, which led to changes in how exit simloop events are handled to make this easier.
src/arch/alpha/isa/decoder.isa:
src/mem/cache/cache_impl.hh:
modify arg. order for new calling convention of exitSimLoop.
src/cpu/base.cc:
src/sim/main.cc:
src/sim/pseudo_inst.cc:
src/sim/root.cc:
now, instead of creating a new SimLoopExitEvent, call a wrapper schedExitSimLoop which handles all the default args.
src/sim/sim_events.cc:
src/sim/sim_events.hh:
src/sim/sim_exit.hh:
add the periodicity of checkpointing back into the code.
to facilitate this, there are now two wrappers (instead of just overloading exitSimLoop). exitSimLoop is only for exiting NOW (i.e. at curTick), while schedExitSimLoop schedules and exit event for the future.
