From: John Hubbard <jhubbard@xxxxxxxxxx> Subject: mm/memory_hotplug.c: remove unused local zone_type from __remove_zone() __remove_zone() sets up up zone_type, but never uses it for anything. This does not cause a warning, due to the (necessary) use of -Wno-unused-but-set-variable. However, it's noise, so just delete it.
