From db7f37de2c8346c33cf9279fa9d8e8316e8d821c Mon Sep 17 00:00:00 2001 From: Tony Breeds Date: Tue, 1 Jul 2008 11:30:06 +1000 Subject: [PATCH] powerpc: Fix building of arch/powerpc/mm/mem.o when MEMORY_HOTPLUG=y and SPARSEMEM=n Currently the kernel fails to build with the above config options with: CC arch/powerpc/mm/mem.o arch/powerpc/mm/mem.c: In function 'arch_add_memory': arch/powerpc/mm/mem.c:130: error: implicit declaration of function 'create_section_mapping' This explicitly includes asm/sparsemem.h in arch/powerpc/mm/mem.c and moves the guards in include/asm-powerpc/sparsemem.h to protect the SPARSEMEM specific portions only.
