Thanks Nilay.  I have couple comments below.


src/mem/ruby/system/RubyPort.cc
<http://reviews.gem5.org/r/2466/#comment4903>

    This comment should be updated.



src/mem/ruby/system/System.hh
<http://reviews.gem5.org/r/2466/#comment4904>

    Making this a static variable seems dangerous.  With this change, one could 
not use a ruby protocol that needs a backing store (second copy of phys mem) in 
multi-system simulation.
    
    Can you make it non-static instead?
