On ppc, we got this build error with randconfig: drivers/built-in.o:(.toc1+0xf90): undefined reference to `vmstat_text': 1 errors in 1 logs This is due to that it enabled CONFIG_NUMA but not CONFIG_SYSFS. And the user-space tool numactl depends on sysfs files too. So, I think it is very reasonable to make CONFIG_NUMA depend on CONFIG_SYSFS.
