When I first introduced vmemmap manipulation functions related to HugeTLB, I thought those functions may be reused by other modules (e.g. using similar approach to optimize vmemmap pages, unfortunately, the DAX used the same approach but does not use those functions). After two years, we didn't see any other users. So move those functions to hugetlb_vmemmap.c. Code movement without any functional change.
