No. It's a matter of abstraction. If you can _abstract_ the thing away, that's fine. I don't want more #ifdef's in source code, but you can have a totally different file that doesnt' do the things that aren't appropriate for non-MMU.
Yes, we've already got #ifdef's in code, but the point is that we don't add them unless there is serious _need_. And even then it's a sign of trouble. In this case, the sign of trouble is bigger than the need. uClinux might as well have a dummy "struct vm_operations", if only to make the damn thing look more like real Linux.
