I'm not proposing we remove anything :-) It would just be nice
to eliminate the overhead of managing the PTEs if we don't
need such a feature. The complexity of the TLB miss handler
just keeps growing to add/fix this stuff, and it really shouldn't
be in that code path. All of this support should be pushed
into the error path, and if it was somewhat configurable we
wouldn't be in that path if not necessary.
Thanks.
