If you want to simulate a "CMP" with 2 processors, each with private L1-L2
hierarchies, then just use the SMP protocols as-is and configure your
interconnect to be really fast like a "CMP".  Use g_PROCS_PER_CHIP as "1".
Yes, the simulator thinks there are 2 "chips" but if your interconnect is
configured to be fast, then it doesn't matter.
