mm/hugetlb: convert hugetlb_install_page to folios
Patch series "convert hugetlb fault functions to folios", v2. This series converts the hugetlb page faulting functions to operate on folios. These include hugetlb_no_page(), hugetlb_wp(), copy_hugetlb_page_range(), and hugetlb_mcopy_atomic_pte(). This patch (of 8): Change hugetlb_install_page() to hugetlb_install_folio(). This reduces one user of the Huge Page flag macros which take in a page.
