gem5::BaseCache::CacheCmdStats::CacheCmdStats  (  BaseCache &  c, 
const std::string &  name ) 
void gem5::BaseCache::CacheCmdStats::regStatsFromParent  (  ) 
Callback to register stats from parent CacheStats::regStats().
We can't use the normal flow since there is is no guaranteed order and CacheStats::regStats() needs to rely on these stats being initialised.
