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.

8d53f298a6 Caches return a new functional port whenever asked for one.
src/mem/cache/base_cache.cc:
    Have caches return a new functional port whenever asked for them.  I'm pretty sure this is desired behavior.  Ron can correct me if it's not.

4da3938ed9 get rid of the "resume" step at the end of changeToTiming/Atomic because this will cause an assertion when you do the CPU switch. instead, push the responsibility of the resume upwards towards the user - documented in se.py and fs.py so it should be ok.
