Hi Pablo,

Argh - there is one more CONFIG option combi that can cause issues.

  *So hold off on this patch*

Which is related to including linux/netfilter_ipv6/ip6_tables.h under 
CONFIG_IPV6 when CONFIG_NETFILTER is disabled, as kernel/sysctl_binary.c 
include net/ip_vs.h.  I'll send a new patch soon!
