Turns out, this breaks the build if netfilter is *disabled*, because I forgot to
add a stub in that case.  Next version of patch (if there is one) will have the
following under #ifndef CONFIG_NETFILTER:

static inline void
NF_HOOK_LIST(uint8_t pf, unsigned int hook, struct net *net, struct sock *sk,
	     struct sk_buff_head *list, struct sk_buff_head *sublist,
	     struct net_device *in, struct net_device *out,
	     int (*okfn)(struct net *, struct sock *, struct sk_buff *))
{
	__skb_queue_head_init(sublist);
	/* Move everything to the sublist */
	skb_queue_splice_init(list, sublist);
}
