But I want TLB load instructions. TLB load instructions + hardware walking just do not make much sense if you allow the loaded entries to be victimized. Of course, you can have a separate "lock this TLB entry that I give you" thing, which can be useful for real-time, and can also be useful for having per-CPU data areas. But then you might as well consider that a BAT register ("block address translation", ppc has those too), and separate from the TLB.
