From 81d0d950e5037a26b71e568ff235ff9e998f4ab3 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Sat, 27 Feb 2010 09:29:38 -0800 Subject: sparsemem: Fix compilation on PowerPC Stephen reported: build (powerpc ppc64_defconfig) produced these warnings: mm/sparse.c: In function 'sparse_init': mm/sparse.c:488: warning: unused variable 'map_count' mm/sparse.c:484: warning: unused variable 'size2' mm/sparse.c:481: warning: unused variable 'map_map' mm/sparse.c: At top level: mm/sparse.c:442: warning: 'sparse_early_mem_maps_alloc_node' defined but not used Introduced by commit 9bdac914240759457175ac0d6529a37d2820bc4d ("sparsemem: Put mem map for one node together"). Conditionalize the bits appropriately based on the setting of CONFIG_SPARSEMEM_ALLOC_MEM_MAP_TOGETHER.
