linux-next: build failure after merge of the net-next tree

Hi all,

After merging the net-next tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

In file included from net/netfilter/utils.c:5:
include/linux/netfilter_ipv6.h: In function 'nf_ipv6_br_defrag':
include/linux/netfilter_ipv6.h:110:9: error: implicit declaration of function 'nf_ct_frag6_gather'; did you mean 'nf_ct_attach'? [-Werror=implicit-function-declaration]
  return nf_ct_frag6_gather(net, skb, user);
         ^~~~~~~~~~~~~~~~~~
         nf_ct_attach

Caused by commit

  764dd163ac92 ("netfilter: nf_conntrack_bridge: add support for IPv6")

CONFIG_IPV6 is not set for this build.

I have reverted that commit for today.
