Content preview: Hi, Big pile of ARC mm changes to prepare for 3 or 4 levels of paging (from current 2) needed for new hardware page walked MMUv6 (in aRCv3 ISA based cores). Most of these changes are incremental cleanups to make way for 14/18 and 15/18 which actually imeplement the new levels (in existing ARCv2 port) and worth a critical eye.
