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.
