From: "Mike Rapoport (Microsoft)" <[email protected]> Move calculations of zone limits to a dedicated arch_zone_limits_init() function. Later MM core will use this function as an architecture specific callback during nodes and zones initialization and thus there won't be a need to call free_area_init() from every architecture.
