The real reason I want to "close" hugetlb regions (even on 64bit platforms) is so a process can replace a previous hugetlb mapping with normal pages when huge pages become scarce. An example would be the hugetlb morecore (malloc) feature in libhugetlbfs :)Well that approach wont work on IA64 it seems.
