mm: add new arch_make_huge_pte() method for tile support The tile support for multiple-size huge pages requires tagging the hugetlb PTE with a "super" bit for PTEs that are multiples of the basic size of a pagetable span. To set that bit properly we need to tweak the PTe in make_huge_pte() based on the vma. This change provides the API for a subsequent tile-specific change to use.
