I think the fact that large page support doesn't support mmap for users
that need it is utterly appauling; there are numerous places where it is
needed. The requirement for root-only access makes it useless for most
people, especially in HPC environments where it is most needed as such
machines are usually shared and accounts are non-priveledged.
