Hi Cong,
Today's linux-next merge of the kmap_atomic tree got a conflict in
drivers/net/ethernet/intel/e1000e/netdev.c between commit 0e15df490eef
("e1000e: minor whitespace and indentation cleanup") from the net-next
tree and commit 2b4ba510a572 ("net: remove the second argument of k
[un]map_atomic()") from the kmap_atomic tree.
I fixed it up (see below) and can carry the fix as necessary.
