It would be nicer to keep things in the positive-logic sense if at all
possible: flags that indicate "we don't want something" tend to end up
with double or triple negatives somewhere which makes understanding
the code much harder.  It's a shame we have MADV_NOHUGEPAGE...

That's not a strong view, but a preference.
