Do you need to?

In the mainstream, the TLB does both mapping and protection; whereas in the Mill, translation is just mapping. Protection (turf reminds me of ‘get off my lawn’) is fast and between load/store FU and the top of the cache, whereas TLB is much slower but between the bottom of the cache and main memory (which is even slower anyway).
