From f9872caf07c1c774034b8bddde7d4a3a7f4a6484 Mon Sep 17 00:00:00 2001 From: Cody P Schafer Date: Mon, 29 Apr 2013 15:08:01 -0700 Subject: [PATCH] page_alloc: make setup_nr_node_ids() usable for arch init code powerpc and x86 were opencoding copies of setup_nr_node_ids(), which page_alloc provides but makes static. Make it avaliable to the archs in linux/mm.h.
