Hi Dave,

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

Caused by commit 1d7138de878d1d4210727c1200193e69596f93b3 ("igmp: RCU

for_each_pmc_rcu definitions are protected by  CONFIG_IP_MULTICAST, but
the uses are not ...

I have reverted that commit for today.
