mm/hugetlb: use a folio in copy_hugetlb_page_range()
Patch series "Convert several functions in hugetlb.c to use a folio", v2.
This patch series converts three functions in hugetlb.c to use a folio,
which can remove several implicit calls to compound_head().
This patch (of 3):
We can replace five implict calls to compound_head() with one by using
pte_folio. The page we get back is always a head page, so we just convert
ptepage to pte_folio.
