  not sure if this is still the right ML, but here's the equivalent
unreferenced content under arch/powerpc:

========== FC_ENET_HAS_SCC ==========
arch/powerpc/platforms/8xx/mpc885ads_setup.c:109:#ifndef CONFIG_FC_ENET_HAS_SCC
========== SMP_750 ==========
arch/ppc/mm/tlb.c:92:#ifdef CONFIG_SMP_750
arch/powerpc/mm/tlb_32.c:92:#ifdef CONFIG_SMP_750
========== SPE_BASE ==========
arch/powerpc/mm/hash_utils_64.c:612:#ifdef CONFIG_SPE_BASE
arch/powerpc/mm/hash_utils_64.c:747:#ifdef CONFIG_SPE_BASE
