2010-08-20	ruby: added probe filter support to hammer	Brad Beckmann

2010-08-20	ruby: Disable migratory sharing for token and hammer	Brad Beckmann
	This patch allows one to disable migratory sharing for those cache blocks that are accessed by atomic requests. While the implementations are different between the token and hammer protocols, the motivation is the same. For Alpha, LLSC semantics expect that normal loads do not unlock cache blocks that have been locked by LL accesses. Therefore, locked blocks should not transfer write permissions when responding to these load requests. Instead, only they only transfer read permissions so that the subsequent SC access can possibly succeed.
2010-08-20	ruby: Reduced ruby latencies	Brad Beckmann
	The previous slower ruby latencies created a mismatch between the faster M5 cpu models and the much slower ruby memory system. Specifically smp interrupts were much slower and infrequent, as well as cpus moving in and out of spin locks. The result was many cpus were idle for large periods of time. These changes fix the latency mismatch.
2010-08-20	memtest: Memtester support for DMA	Brad Beckmann
	This patch adds DMA testing to the Memtester and is inherits many changes from Polina's old tester_dma_extension patch. Since Ruby does not work in atomic mode, the atomic mode options are removed.
2010-08-20	config: Improve ruby simobject names	Brad Beckmann
	This patch attaches ruby objects to the system before the topology is created so that their simobject names read their meaningful variable names instead of their topology name.
