Hi all,

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

net/bridge/br_nf_core.c:77:1: error: expected identifier or '(' before '{' token
 {
 ^

Caused by commit 34666d467cbf ("netfilter: bridge: move br_netfilter
out of the core").  This build has CONFIG_BRIDGE_NETFILTER not set ...

I have applied the following patch for today:

From: Stephen Rothwell <redacted>
Date: Tue, 30 Sep 2014 13:09:09 +1000
Subject: [PATCH] netfilter: bridge: don't build br_nf_core unless necessary
