Jing Qu	aff2cad4be	mem-ruby: prevent cacheProbe being called multiple times ... The cacheProbe() function will return the victim entry, and it gets called for multiple times in trigger function in a single miss. This will cause a problem when we try to add a new replacement policy to the Ruby system. Certain policy, like RRIP, will modify the block information every time the getVictim() function gets called. To prevent future problems, we need to store the victim entry, so that we only call it once in one miss.

Gabe Black	c08351f4d3	mem: Move ruby protocols into a directory called ruby_protocol. ... Now that the gem5 protocols are split out, it would be nice to put them in their own protocol directory. It's also confusing to have files called *_protocol which are not in the protocol directory.
