Hi all,

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

net/bridge/br_multicast.c: In function 'br_multicast_has_querier_adjacent':

Caused by commit 2cd4143192e8 ("bridge: memorize and export selected
IGMP/MLD querier port").  This build has CONFIG_IPV6 not set.

I have reverted that commit for today.
