9098010e3f slicc: tweak file enumeration for scons 
Right now .cc and .hh files are handled separately, but then
they're just munged together at the end by scons, so it
doesn't buy us anything.  Might as well munge from the start
since we'll eventually be adding generated Python files
to the list too.

2009.  This relicensing was in an explicit e-mail to Nathan Binkert,

72cfed4164 Force prefetches to check cache and MSHRs immediately prior to issue. 
This prevents redundant prefetches from being issued, solving the
occasional 'needsExclusive && !blk->isWritable()' assertion failure
in cache_impl.hh that several people have run into.
Eliminates "prefetch_cache_check_push" flag, neither setting of
which really solved the problem.

33b28fde7a slicc: added MOESI_CMP_directory, DMA SequencerMsg, parameterized controllers 
This changeset contains a lot of different changes that are too
mingled to separate.  They are:

1.  Added MOESI_CMP_directory

I made the changes necessary to bring back MOESI_CMP_directory,
including adding a DMA controller.  I got rid of MOESI_CMP_directory_m
and made MOESI_CMP_directory use a memory controller. Added a new
configuration for two level protocols in general, and
MOESI_CMP_directory in particular.

2.  DMA Sequencer uses a generic SequencerMsg

I will eventually make the cache Sequencer use this type as well.  It
doesn't contain an offset field, just a physical address and a length.
MI_example has been updated to deal with this.

3. Parameterized Controllers

SLICC controllers can now take custom parameters to use for mapping,
latencies, etc.  Currently, only int parameters are supported.

c0755e6085 Rename internal Request fields to start with '_'. 
The inconsistency was causing a subtle bug with some of the
constructors where the params had the same name as the fields.
This is also a first step to switching the accessors over to
our new "standard", e.g., getVaddr() -> vaddr().

d51445490d regression: updated memtest-ruby stats 
This also includes a change to the default Ruby random seed, which was

the stat files don't change for the regression tester.
