7245d4530d refactor code for the packet, get rid of packet_impl.hh
and call it packet_access.hh and fix the #includes so
things compile right.

780aa0a0eb Fix corner case on assertion.
I need to move over to using the fixPacket function so I don't have to make the same changes everywhere.
Still a functional access bug someplace I need to track down in timing mode.

src/mem/cache/base_cache.cc:
src/mem/cache/cache_impl.hh:
    Fix corner case on assertion
tests/configs/memtest.py:
    Updated memtester with uncacheable addresses and functional accesses

cc1feb9f6d Fix memtester to use functional access, fix cache to work functionally now that we could test it.
src/cpu/memtest/memtest.cc:
    Fix memtest to do functional accesses
src/mem/cache/cache_impl.hh:
    Fix cache to handle functional accesses properly based on memtester changes
    Still need to fix functional accesses in timing mode now that the memtester can test it.

210e73f2a2 Small changes:
?? doesn't compile in warn statements
Should have been false, where I had a true.

src/cpu/o3/lsq_impl.hh:
    Apparently you can't have ?? in a warn statement (Something about trigraphs)
src/mem/cache/cache_impl.hh:
    Forgot to signal atomic mode in snoopProbe
