yup, people will presumably work on fixing these things up after the feature hits mainline.

Ah. I assume you have CONFIG_SYSCTL=y, CONFIG_PROC_SYSCTL=n?
From: Andrew Morton <akpm@linux-foundation.org>
We're using #ifdef CONFIG_SYSCTL, but we should be using CONFIG_PROC_SYSCTL, so we get
fs/built-in.o: In function `proc_root_init': /usr/src/linux/fs/proc/root.c:83: undefined reference to `proc_sys_init'
Fix that up and remove an ifdef-in-C.
