The second build error was tricky, and can occur when deselecting both all Netfilter and IPVS, but selecting CONFIG_IPV6. This is caused by "kernel/sysctl_binary.c" including "net/ip_vs.h", which includes "linux/netfilter_ipv6/ip6_tables.h" causing include of "include/linux/netfilter/x_tables.h" which then cannot find the typedef nf_hookfn. Fix this by only including "linux/netfilter_ipv6/ip6_tables.h" in case of CONFIG_IP_VS_IPV6 as its already used to guard the usage of ipv6_find_hdr().
