[PATCH] mm/memory_hotplug: move definitions of {set,clear}_zone_contiguous

From: Ben Dooks (Codethink)
Date: Wed Nov 06 2019 - 07:39:23 EST


The {set,clear}_zone_contiguous are built whatever the
configuraiton so move the definitions outside the current
ifdef to avoid the following compiler warnings:

mm/page_alloc.c:1550:6: warning: no previous prototype for Ãset_zone_contiguousà [-Wmissing-prototypes]
mm/page_alloc.c:1571:6: warning: no previous prototype for Ãclear_zone_contiguousà [-Wmissing-prototypes]
