f8fc0419c5 X86, Config: Move the setting of work count options to a separate function.
This way things that don't care about work count options and/or aren't called
by something that has those command line options set up doesn't have to build
a fake object to carry in inert values.

00f24ae92c Config: Keep track of uncached and cached ports separately.
This makes sure that the address ranges requested for caches and uncached ports
don't conflict with each other, and that accesses which are always uncached
(message signaled interrupts for instance) don't waste time passing through
caches.

a368fba7d4 Time: Add a mechanism to prevent M5 from running faster than real time.
M5 skips over any simulated time where it doesn't have any work to do. When
the simulation is active, the time skipped is short and the work done at any
point in time is relatively substantial. If the time between events is long
and/or the work to do at each event is small, it's possible for simulated time
to pass faster than real time. When running a benchmark that can be good
because it means the simulation will finish sooner in real time. When
interacting with the real world through, for instance, a serial terminal or
bridge to a real network, this can be a problem. Human or network response time
could be greatly exagerated from the perspective of the simulation and make
simulated events happen "too soon" from an external perspective.

This change adds the capability to force the simulation to run no faster than
real time. It does so by scheduling a periodic event that checks to see if
its simulated period is shorter than its real period. If it is, it stalls the
simulation until they're equal. This is called time syncing.

A future change could add pseudo instructions which turn time syncing on and
off from within the simulation. That would allow time syncing to be used for
the interactive parts of a session but then turned off when running a
benchmark using the m5 utility program inside a script. Time syncing would
probably not happen anyway while running a benchmark because there would be
plenty of work for M5 to do, but the event overhead could be avoided.

6629d9b2bc mem: use single BadAddr responder per system.
Previously there was one per bus, which caused some coherence problems
when more than one decided to respond.  Now there is just one on
the main memory bus.  The default bus responder on all other buses
is now the downstream cache's cpu_side port.  Caches no longer need
to do address range filtering; instead, we just have a simple flag
to prevent snoops from propagating to the I/O bus.

0ba2cc6571 Clean up config scripts to not have to worry about attaching a cache only to the TimingCPU. Now the Atomic CPU works with caches.
configs/common/Simulation.py:
    Atomic CPU now works properly with caches, so we don't have to do extra parsing to hook up caches only to the timing CPU.

    However the O3CPU must always use caches, so a check for that must still exist.

    Also change the switch_cpus to be placed at the system level, now that Steve changed how the IntrController gets its CPU.

40a04f2f40 changes regarding fs.py
1) rearrange the options to be in a nice logical order
2) add an option for what i call "standard switch", which is from simple->timing->detailed
3) change the client/server naming system to testsys/drivesys
4) make checkpointing code such that checkpoints taken from the command line override checkpoint instructions compiled into binaries.
5) add an option for maximum number of checkpoints - simulation will stop at max or maxtick, whichever is first

doesn't fully work because of a caching issue, but the python side of things i think should work - the counterpart of se.py does work.
i think i should factor out a lot of the common code in both, but i'll do that after this checkin, just to get this in the tree.
