I'm not sure. Stores for sure, loads I'm not sure about. I suspect loads are OK, the aliasing cacheline will be !modified and therefore later eviction should discard (not write back). But like said, I'm not at all sure. I would hesitate to put such assumptions into generic code -- although it appears we already have. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
