c779af4e12 Mem: Finish half-baked support for mmaping file in physmem.
Physmem has a parameter to be able to mem map a file, however
it isn't actually used. This changeset utilizes the parameter
so a file can be mmapped.

29c45ccd23 ruby: Reduced ruby latencies
The previous slower ruby latencies created a mismatch between the faster M5
cpu models and the much slower ruby memory system.  Specifically smp
interrupts were much slower and infrequent, as well as cpus moving in and out
of spin locks.  The result was many cpus were idle for large periods of time.

These changes fix the latency mismatch.

2519d116c9 sim: fold checkpoint restore code into instantiate()
The separate restoreCheckpoint() call is gone; just pass
the checkpoint dir as an optional arg to instantiate().
This change is a precursor to some more extensive
reworking of the startup code.

cfaddd5fd3 configs: clean up checkpoint code in Simulation.py
Small change to clean up some redundant code.

1fbe466345 sim: make Python Root object a singleton
Enforce that the Python Root SimObject is instantiated only
once.  The C++ Root object already panics if more than one is
created.  This change avoids the need to track what the root
object is, since it's available from Root.getInstance() (if it
exists).  It's now redundant to have the user pass the root
object to functions like instantiate(), checkpoint(), and
restoreCheckpoint(), so that arg is gone.  Users who use
configs/common/Simulate.py should not notice.

a70f70ccbf configs: pull out cache configuration code from se.py and fs.py.
Most of these frontend configurations share cache configuration code, pull it out so that
changes to caches don't have to require changing multiple config files.

dc758641c9 ruby: reorganized ruby python configuration
Reorganized ruby python configuration so that protocol and ruby memory system
configuration code can be shared by multiple front-end configuration files
(i.e. memory tester, full system, and hopefully the regression tester).  This
code works for memory tester, but have not tested fs mode.

ports.

-option to allow threads to run to a max_inst_any_thread which is more useful/quicker in a lot of

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.
