This new one (added by unify_pfn_to_page patches) is obviously buggy. This macro calculate page offset in a node. Note: about LOCAL_MAP_NR() comment in arm's sub-archs says... /* * Given a kaddr, LOCAL_MAP_NR finds the owning node of the memory * and returns the index corresponding to the appropriate page in the * node's mem_map. */ but LOCAL_MAP_NR() is designed to be able to take both paddr and kaddr. In this case, paddr is better.
