Subject: linux-next: build failure after merge of the akpm tree
Hi Andrew,
After merging the akpm tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:
drivers/net/ethernet/mellanox/mlx4/en_rx.c: In function 'mlx4_en_process_rx_cq':
drivers/net/ethernet/mellanox/mlx4/en_rx.c:628:53: error: macro "hlist_for_each_entry_rcu" passed 4 arguments, but takes just 3
drivers/net/ethernet/mellanox/mlx4/en_rx.c:628:5: error: 'hlist_for_each_entry_rcu' undeclared (first use in this function)
drivers/net/ethernet/mellanox/mlx4/en_rx.c:628:55: error: expected ';' before '{' token
Caused by commit c07cb4b0ab78 ("net/mlx4_en: Manage hash of MAC addresses
per port") from the net-next tree interacting with commit "hlist: drop
the node parameter from iterators" from the akpm tree.
I applied the following merge fix patch for today:

That then lead to these:
