Subject: mm/hugetlb: convert hugetlb_install_page to folios
Date: Wed, 25 Jan 2023 09:05:30 -0800

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.
