Subject: [PATCH net-next] netdev: set __percpu attribute on
netdev_alloc_pcpu_stats
This patch fixes sparse warnings in vlan driver.
It propagates the sparse __percpu attribute from alloc_percpu
into netdev_alloc_pcpu_stats. I expect it may trigger additional
sparse warnings from other drivers that are missing the __percpu
attribute.
