These are the stats in the base class, not in any derived classes. Only Alpha has an additional stats. These were not really "kernel" statistics, they were just applicable primarily in FS. They are potentially applicable to any simulation, but will probably not be incremented in SE simulations. Also this merges these stats from being per thread to being per workload, ie operating system instance. This is probably more relevant since exactly what thread within a workload runs which particular instruction is not very important/predictable, but the aggregate behavior is. If necessary, this could be adjusted in the future to split things back out again into stats per thread while keeping them inside the single workload object.
