Make use of the new functionality in walk_page_range to remove the arch page walking code and use the generic code to walk the page tables. The effective permissions are passed down the chain using new fields in struct pg_state. The KASAN optimisation is implemented by setting action=CONTINUE in the callbacks to skip an entire tree of entries.
