Subject: linux-next: build failure after merge of the netfilter-next tree

Hi all,

After merging the netfilter tree, today's linux-next build (powerpc
ppc44x_defconfig) failed like this:

In file included from /home/sfr/next/next/net/bridge/br_input.c:19:
/home/sfr/next/next/include/net/netfilter/nf_queue.h:16:23: error: field 'state'
 has incomplete type
  struct nf_hook_state state;
                       ^~~~~

Caused by commit

  971502d77faa ("bridge: netfilter: unroll NF_HOOK helper in bridge input path")

This build has CONFIG_NETFILTER not set.

I have applied this patch for today:
