Hugh Dickins 457a98b080 mm, x86: fix pte_page() crash in gup_pte_range() ... Commit 3565fce3a6 ("mm, x86: get_user_pages() for dax mappings") has moved up the pte_page(pte) in x86's fast gup_pte_range(), for no discernible reason: put it back where it belongs, after the pte_flags check and the pfn_valid cross-check. That may be the cause of the NULL pointer dereference in gup_pte_range(), seen when vfio called vaddr_get_pfn() when starting a qemu-kvm based VM.
