694323b7c4 Move around misc reg code
src/arch/sparc/faults.cc:
    Moved some code here from miscregfile.cc
src/arch/sparc/miscregfile.cc:
    Moved code from here to faults.cc, and merged (read|set)MiscRegWithEffect and it's FS version from ua2005.cc
src/arch/sparc/miscregfile.hh:
    readFSRegWithEffect is no longer a seperate function, and is instead done in the main readRegWith Effect.

45363ea658 Have bus use the BadAddress device to handle bad addresses. The O3 CPU should be able to boot into Linux with caches on after this change.
src/mem/bus.cc:
src/mem/bus.hh:
    Bus now will be setup with a default responder, unless the user overrides it.  This default responder should return BadAddress if no matching port is found.
src/python/m5/objects/Bus.py:
    Bus now has a default responder for FS mode if the user doesn't override it.  It returns BadAddress if no matching port is found.
src/python/m5/objects/Tsunami.py:
    Add bad address device.  Also record when the user has specified their own default responder.

d52117d1e3 add in serialization of AtomicSimpleCPU _status. This is needed because right now unserializing breaks an assert since CPU status is not saved. Kev says that this will break uniform serialization across CPUs since each type of CPU has its own "status" enum set. So, the repercussions are that if you serialize in this CPU, you must first unserialize in this CPU before switching to something else you want.
