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

Hi all,

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

drivers/net/virtio_net.c: In function 'try_fill_recv':
drivers/net/virtio_net.c:1250:3: error: too few arguments to function 'u64_stats_update_end_irqrestore'
 1250 |   u64_stats_update_end_irqrestore(&rq->stats.syncp);
      |   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

                 from include/linux/netdevice.h:38,

  149 | u64_stats_update_end_irqrestore(struct u64_stats_sync *syncp,
      | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Caused by commit

  fa74db4261e1 ("virtio_net: fix lockdep warning on 32 bit")

I have used the version of the vhost tree from next-20200505.
