The pagetable walk callbacks in mm/mapping_dirty_helpers.c depend on a set of helpers from which pud_dirty(pud) was missing. I'm assuming mapping_dirty_helpers weren't used on ARM64 before because the missing pud_dirty is causing a compilation error.
The drivers/gpu/drm/vmwgfx code uses mapping_dirty_helpers and has been ported to ARM64 but it depends on this code getting in first in order to compile/work.
