651cfbab03 network: adjusted default endpoint bandwidth
The simple network's endpoint bandwidth value is used to adjust the overall
bandwidth of the network.  Specifically, the ration between endpoint bandwidth
and the MESSAGE_SIZE_MULTIPLIER determines the increase.  By setting the value
to 1000, that means the bandwdith factor specified in the links translates to
the link bandwidth in bytes.  Previously, it was increasing that value by 10.

This patch will likely require a reset of the ruby regression tester stats.

491cc1a9f4 network: moved network config params
Moved the buffer_size, endpoint_bandwidth, and adaptive_routing params out of
the top-level parent network object and to only those networks that actually
use those parameters.

8733ed4b7d network: basic link bw for garnet and simple networks
This patch ensures that both Garnet and the simple networks use the bw value
specified in the topology.  To do so, the patch generalizes the specification
of bw for basic links.  This value is then translated to the specific value
used by the simple and Garnet networks.  Since Garent does not support
non-uniformed link bandwidth, the patch also adds a check to ensure all bws are
equal.

40bcbf4253 network: convert links & switches to first class C++ SimObjects
This patch converts links and switches from second class simobjects that were
virtually ignored by the networks (both simple and Garnet) to first class
simobjects that directly correspond to c++ ojbects manipulated by the
topology and network classes.  This is especially true for Garnet, where the
links and switches directly correspond to specific C++ objects.

By making this change, many aspects of the Topology class were simplified.

9e3cdbf516 base: include types.hh in base/stats/mysql.hh
Due to certain changes made via changeset 8229, the compilation was failing
in certain cases. The compiler pointed to base/stats/mysql.hh for not naming
a certain types like uint64_t. To rectify this, base/types.hh is being
included in base/stats/mysql.hh.

0554885eb9 X86: When decoding a memory only inst, fault on reg encodings, don't assert.
This change makes the decoder figure out if an instruction that only supports
memory is using a register encoding and decodes directly to "Unknown" which will
behave appropriately. This prevents other parts of the instruction creation
process from seeing the mismatch and asserting.

3182913e94 scons: make a flexible system for guarding source files
This is similar to guards on mercurial queues and they're used for selecting
which files are compiled into some given object.  We already do something
similar, but it's mostly hard coded for the m5 binary and the m5 library
and I'd like to make it more flexible to better support the unittests

eddac53ff6 trace: reimplement the DTRACE function so it doesn't use a vector

have broader usage than simply tracing.  This means that
--trace-flags is now --debug-flags and --trace-help is now --debug-help

07815c3379 region: add a utility class for keeping track of regions of some range
This is basically like the range_map stuff in src/base (range already
exists in Python).  This code is like a set of ranges.  I'm using it
to keep track of changed lines in source code, but it could be use to
keep track of memory ranges and holes in memory regions.  It could
also be used in memory allocation type stuff.  (Though it's not at all
optimized.)

6b69890493 ARM: Fix checkpoint restoration into O3 CPU and the way O3 switchCpu works.
This change fixes a small bug in the arm copyRegs() code where some registers
wouldn't be copied if the processor was in a mode other than MODE_USER.
Additionally, this change simplifies the way the O3 switchCpu code works by
utilizing TheISA::copyRegs() to copy the required context information
rather than the adhoc copying that goes on in the CPU model. The current code
makes assumptions about the visibility of int and float registers that aren't
true for all architectures in FS mode.
