Mike Rapoport b19bd1c976 mm/mmzone.h: simplify is_highmem_idx() ... There is a lot of historical ifdefery in is_highmem_idx() and its helper zone_movable_is_highmem() that was required because of two different paths for nodes and zones initialization that were selected at compile time. Until commit 3f08a302f5 ("mm: remove CONFIG_HAVE_MEMBLOCK_NODE_MAP option") the movable_zone variable was only available for configurations that had CONFIG_HAVE_MEMBLOCK_NODE_MAP enabled so the test in zone_movable_is_highmem() used that variable only for such configurations. For other configurations the test checked if the index of ZONE_MOVABLE was greater by 1 than the index of ZONE_HIGMEM and then movable zone was considered a highmem zone. Needless to say, ZONE_MOVABLE - 1 equals ZONE_HIGHMEM by definition when CONFIG_HIGHMEM=y. Commit 3f08a302f5 ("mm: remove CONFIG_HAVE_MEMBLOCK_NODE_MAP option") made movable_zone variable always available. Since this variable is set to ZONE_HIGHMEM if CONFIG_HIGHMEM is enabled and highmem zone is populated, it is enough to check whether zone_idx == ZONE_MOVABLE && movable_zone == ZONE_HIGMEM to test if zone index points to a highmem zone. Remove zone_movable_is_highmem() that is not used anywhere except is_highmem_idx() and use the test above in is_highmem_idx() instead.
