mm, hugetlb: integrate giga hugetlb more naturally to the allocation path
Gigantic hugetlb pages were ingrown to the hugetlb code as an alien specie with a lot of special casing. The allocation path is not an exception. Unnecessarily so to be honest. It is true that the underlying allocator is different but that is an implementation detail. This patch unifies the hugetlb allocation path that a prepares fresh pool pages. alloc_fresh_gigantic_page basically copies alloc_fresh_huge_page logic so we can move everything there. This will simplify set_max_huge_pages which doesn't have to care about what kind of huge page we allocate.
