We take a little step forward by passing the dsa device point to the
driver, thus allowing it to perform resource allocations using the
normal mechanisms. This device structure will later be replaced by the
devices own device structure.
Future patches will add a true driver probe function, so we rename the

it is actually about ports enabled to the outside world. So rename it to

locking of the xmit function. The fact that watchdog_timeo was not set and

Notable parts of this set include:
(1) A fix for the AFS filesystem to wait for outstanding calls to complete

(2) Differentiation of local and remote abort codes. At a future point
userspace will get to see this via control message data on recvmsg().
(3) Absorb the rxkad module into the af_rxrpc module to prevent a dependency

net: ipv4: Consider failed nexthops in multipath routes

15.0.0.0/16
nexthop via 12.0.0.2 dev swp1 weight 1
nexthop via 12.0.0.3 dev swp1 weight 1
...
If the link between tor3 and tor1 is down and the link between tor1
and tor2 then tor1 is effectively cut-off from h1. Yet the route lookups
in h1 are alternating between the 2 routes: ping 15.0.0.5 gets one and
ssh 15.0.0.5 gets the other. Connections that attempt to use the
12.0.0.2 nexthop fail since that neighbor is not reachable:
root@h1:~# ip neigh show
...
12.0.0.3 dev swp1 lladdr 00:02:00:00:00:1b REACHABLE
12.0.0.2 dev swp1 FAILED
...
The failed path can be avoided by considering known neighbor information
when selecting next hops. If the neighbor lookup fails we have no
knowledge about the nexthop, so give it a shot. If there is an entry
then only select the nexthop if the state is sane. This is similar to
what fib_detect_death does.
To maintain backward compatibility use of the neighbor information is
based on a new sysctl, fib_multipath_use_neigh.

drivers: net: cpsw: drop host_port field from struct cpsw_priv
The host_port field is constantly assigned to 0 and this value has
never changed (since time when cpsw driver was introduced. More over,
if this field will be assigned to non 0 value it will break current
driver functionality.
Hence, there are no reasons to continue maintaining this host_port
field and it can be removed, and the HOST_PORT_NUM and ALE_PORT_HOST
defines can be used instead.

drivers: net: cpsw: fix port_mask parameters in ale calls
ALE APIs expect to receive port masks as input values for arguments
port_mask, untag, reg_mcast, unreg_mcast. But there are few places in
code where port masks are passed left-shifted by cpsw_priv->host_port,
like below:
cpsw_ale_add_vlan(priv->ale, priv->data.default_vlan,
ALE_ALL_PORTS << priv->host_port,
ALE_ALL_PORTS << priv->host_port, 0, 0);
and cpsw is still working just because priv->host_port == 0
and has never ever been changed.
Hence, fix port_mask parameters in ALE APIs calls and drop
"<< priv->host_port" from all places where it's used to
shift valid port mask.

bpf: simplify verifier register state assignments
verifier is using the following structure to track the state of registers:
struct reg_state {
enum bpf_reg_type type;
union {
int imm;
struct bpf_map *map_ptr;
};
};
and later on in states_equal() does memcmp(&old->regs[i], &cur->regs[i],..)
to find equivalent states.
Throughout the code of verifier there are assignements to 'imm' and 'map_ptr'
fields and it's not obvious that most of the assignments into 'imm' don't
need to clear extra 4 bytes (like mark_reg_unknown_value() does) to make sure
that memcmp doesn't go over junk left from 'map_ptr' assignment.
Simplify the code by converting 'int' into 'long'
