Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Conflicts: drivers/net/ethernet/emulex/benet/be_main.c net/core/sysctl_net_core.c net/ipv4/inet_diag.c The be_main.c conflict resolution was really tricky. The conflict hunks generated by GIT were very unhelpful, to say the least. It split functions in half and moved them around, when the real actual conflict only existed solely inside of one function, that being be_map_pci_bars(). So instead, to resolve this, I checked out be_main.c from the top of net-next, then I applied the be_main.c changes from 'net' since the last time I merged. And this worked beautifully. The inet_diag.c and sysctl_net_core.c conflicts were simple overlapping changes, and were easily to resolve. Signed-off-by: David S. Miller <davem@davemloft.net>
