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.
