On ppc, we got this build error with randconfig:

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.
Is it? CONFIG_NUMA is useful even without userspace numactl tool, no?
Yes it is. No direct dependency.
I would rather fix it in ppc.
This isn't a ppc-only error. It happens when CONFIG_PROC_FS is not enabled
(or is it CONFIG_SYSFS?).
I reported it for linux-next of 20110526:
when CONFIG_PROC_FS is not enabled:
drivers/built-in.o: In function `node_read_vmstat':
node.c:(.text+0x56ffa): undefined reference to `vmstat_text'
Right, I believe x86 has the same problem.
