Would it be better off to start off with a new API for this? The

It would be weird because the new API would mostly duplicate this one,
and we would end up with duplicated hooks..

They could just #define one to the other though, there are only a small
number of them. Is there a downside to not making them distinct? i386
for example probably would just keep doing a tlb flush for fork and not
want to worry about touching the tlb gather stuff.
