This patch breaks all the 64-bit configs since 64-bit doesn't have total_lowmem. The extra complexity is only needed in the CONFIG_HIGHMEM case, so an ifdef would be one solution, though an ugly one. We do already have an ifdef just above the place you changed in arch/powerpc/mm/mem.c which you could just enlarge rather than adding a new ifdef. And clearly I can't pull your tree until this is sorted somehow...
