e7fa4f2f8e i8254xGBe: major style overhaul. 
Moved DescCache template functions from .hh to .cc file.
Also fixed lots of line-wrapping problems, and some irregular indentation.

7b40c36fbd Update stats for new single bad-address responder. 
Mostly just config.ini updates, though the different response
latency for bad addresses caused very minor timing changes
in the O3 Linux boot tests.

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.

05d8c9acb8 scons: Rename the basic environment from env -> main. 
env is used as a local variable all over the place and sometimes it is
easy to get confused as to whether the global env or local env is being
used.  This will become especially important when I change the way we
support our variants.

56e5509bfd scons: Fix two problems with the way that the library path is generated. 
1) -L is automatically added, so don't do it ourselves
2) prepend the paths for gzstream and libelf so they are certain to
come first. The problem is that python might add /usr/lib to the path
and the user might have a locally installed version of libelf installed.

7b2f8e6857 Set up m5threads tests on classic (non-ruby) memory system. 
Just one test (40.m5threads-test-atomic) is set up for now.
These tests require that the m5threads SPARC binaries are present
in /dist or in test-progs.

Daniel Sanchez
b0e9654f86 Commit m5threads package. 
This patch adds limited multithreading support in syscall-emulation
mode, by using the clone system call.  The clone system call works
for Alpha, SPARC and x86, and multithreaded applications run
correctly in Alpha and SPARC.

7f8ea68a30 request: split public and private flags into separate fields. 
This frees up needed space for more public flags.  Also:
- remove unused Request accessor methods
- make Packet use public Request accessors, so it need not be a friend

d90456a486 X86: Implement the stul microop. 
This microop does a store and unlocks the requested address. The RISC86
microop ISA doesn't seem to have an equivalent to this, so I'm guessing that
the store following an ldstl is automatically unlocking. We don't do it this
way for performance reasons since the behavior is the same.
