Subject: mm/pagewalk: Use vma_find() instead of vma linked list
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=63e14fa9ee5994ed995ed0c2686d74ea02fac000;p=users%2Fjedix%2Flinux-maple.git

mm/pagewalk: Use vma_find() instead of vma linked list

walk_page_range() no longer uses the one vma linked list reference.
