Hi all,

After merging the net-next tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

In function 'dst_hold',
    inlined from '__ipv6_dev_ac_dec' at /home/sfr/next/next/net/ipv6/anycast.c:328:2:
/home/sfr/next/next/include/linux/compiler.h:447:38: error: call to '__compiletime_assert_243' declared with attribute error: BUILD_BUG_ON failed: offsetof(struct dst_entry, __refcnt) & 63

  ^

And many more :-(

Caused by commit

  61adedf3e3f1 ("route: move lwtunnel state to dst_entry")

I have used the net-next tree from next-20150821 for today.
