Mike Kravetz 1bfad99ab4 hugetlbfs: hugetlb_vmtruncate_list() needs to take a range to delete ... fallocate hole punch will want to unmap a specific range of pages. Modify the existing hugetlb_vmtruncate_list() routine to take a start/end range. If end is 0, this indicates all pages after start should be unmapped. This is the same as the existing truncate functionality. Modify existing callers to add 0 as end of range. Since the routine will be used in hole punch as well as truncate operations, it is more appropriately renamed to hugetlb_vmdelete_list().
