Don't do clock-mode-select if clk == NULL,
since when building without CONFIG_HAVE_CLK,
clk_get returns NULL and clk_get_rate returns 0.
Doing clock-mode-select in this cause causes kszphy_probe to
return -EINVAL and thus prevents the device from being probed.
The original code (before regression) would return 0
when building without CONFIG_HAVE_CLK.

Commit 12a8541d5c "bnx2x: Delay during kdump load" added a 5 seconds
delay to bnx2x's probe function in the kdump case to let the firmware
realize the old driver is gone.
The problem with the delay is that it is per-device, so if you have
several bnx2x NICs in NPAR mode, the delays can accumulate to minutes.
Fix it by adjusting the delay so that we do not wait more than
necessary, i.e. no more delaying after 5 seconds of kernel boot time.

The ARM JIT code emits "ldr rX, [pc, #offset]" to access the literal
pool. #offset maximum value is 4095 and if the generated code is too
large, the #offset value can overflow and not point to the expected
slot in the literal pool. Additionally, when overflow occurs, bits of
the overflow can end up changing the destination register of the ldr
instruction.
Fix that by detecting the overflow in imm_offset() and setting a flag
that is checked for each BPF instructions converted in
build_body(). As of now it can only be detected in the second pass. As
a result the second build_body() call can now fail, so add the
corresponding cleanup code in that case.
Using multiple literal pools in the JITed code is going to require
lots of intrusive changes to the JIT code (which would better be done
as a feature instead of fix), just delegating to the kernel BPF
interpreter in that case is a more straight forward, minimal fix and
easy to backport.

Unfortunately, I didn't check to see where else this lock was used before

did a thorough search this time.
To recap from the original patch; although testing this driver with
DEBUG_LOCKDEP and DEBUG_SPINLOCK enabled did not produce any traces,
it would be more prudent in the case of tx_clean_lock to use _bh
versions of spin_[un]lock, since this lock is manipulated in both

This patch was tested for functionality and regressions with netperf

net/rds: RDS-TCP robustness fixes
This patch-set contains bug fixes for state-recovery at the RDS
layer when the underlying transport is TCP and the TCP state at one
of the endpoints is reset
V2 changes: DaveM comments to reduce memory footprint, follow
NFS/RPC model where possible. Added test-case #3
Without the changes in this set, when one of the endpoints is reset,
the existing code does not correctly clean up RDS socket state for stale
connections, resulting in some unstable, timing-dependant behavior on
the wire, including an infinite exchange of 3WHs back-and-forth, and a
resulting potential to never converge RDS state.
Test cases used to verify the changes in this set are:
1. Start rds client/server applications on two participating nodes,
node1 and node2. After at least one packet has been sent (to establish
the TCP connection), restart the rds_tcp module on the client, and
now resend packets. Tcpdump should show server sending a FIN for the
"old" client port, and clean connection establishment/exchange for
the new client port.
2. At the end of step 1, restart rds srever on node2, and start client on
node1, make sure using tcpdump, 'netstat -an|grep 16385' that
packets flow correctly.
3. start RDS client/server application on two participating nodes, and
repeat steps 1 and 2, but this time, simulate node failure by doing
"ifconfig <intf> down", so no FIN is sent.

When the peer of an RDS-TCP connection restarts, a reconnect
attempt should only be made from the active side of the TCP
connection, i.e. the side that has a transient TCP port
number. Do not add the passive side of the TCP connection
to the c_hash_node and thus avoid triggering rds_queue_reconnect()
for passive rds connections.

When running RDS over TCP, the active (client) side connects to the
listening ("passive") side at the RDS_TCP_PORT. After the connection
is established, if the client side reboots (potentially without even
sending a FIN) the server still has a TCP socket in the esablished
state. If the server-side now gets a new SYN comes from the client
with a different client port, TCP will create a new socket-pair, but
the RDS layer will incorrectly pull up the old rds_connection (which
is still associated with the stale t_sock and RDS socket state).
This patch corrects this behavior by having rds_tcp_accept_one()
always create a new connection for an incoming TCP SYN.
The rds and tcp state associated with the old socket-pair is cleaned
up via the rds_tcp_state_change() callback which would typically be
invoked in most cases when the client-TCP sends a FIN on TCP restart,
triggering a transition to CLOSE_WAIT state. In the rarer event of client
death without a FIN, TCP_KEEPALIVE probes on the socket will detect
the stale socket, and the TCP transition to CLOSE state will trigger
the RDS state cleanup.

If there are only IPv6 source specific default routes present, the
host gets -ENETUNREACH on e.g. connect() because ip6_dst_lookup_tail
calls ip6_route_output first, and given source address any, it fails,
and ip6_route_get_saddr is never called.
The change is to use the ip6_route_get_saddr, even if the initial
ip6_route_output fails, and then doing ip6_route_output _again_ after
we have appropriate source address available.
Note that this is '99% fix' to the problem; a correct fix would be to
do route lookups only within addrconf.c when picking a source address,
and never call ip6_route_output before source address has been
populated.

The code in __netdev_upper_dev_link() has an over-stringent
loop detection logic that actually prevents valid configurations
from working correctly.
In particular, the logic returns an error if an upper device
is already in the list of all upper devices for a given dev.
This particular check seems to be a overzealous as it disallows
perfectly valid configurations. For example:
# ip l a link eth0 name eth0.10 type vlan id 10
# ip l a dev br0 typ bridge
# ip l s eth0.10 master br0
# ip l s eth0 master br0 <--- Will fail
If you switch the last two commands (add eth0 first), then both
will succeed. If after that, you remove eth0 and try to re-add
it, it will fail!
It appears to be enough to simply check adj_list to keeps things
safe.
I've tried stacking multiple devices multiple times in all different
combinations, and either rx_handler registration prevented the stacking
of the device linking cought the error.

====================
Clean-up some bits related to netpoll
This patch set cleans up some minor items related to netpoll. The first
patch addresses an Rx clean-up bug that is triggered due to an assumption
that napi->poll wouldn't be called with a budget of 0. The other two
patches address dev_kfree_skb being called in the xmit path which isn't
valid since netpoll will call ndo_start_xmit with IRQs disabled.

With netpoll making use of the transmit function it is possible for the
ndo_start_xmit function to be called with irqs disabled. As such we need
to use dev_kfree_skb_any in the Tx cleanup path for frames that are
dropped.

The function r8169_csum_workaround is called in the ndo_start_xmit path of
the r8169 driver. As such it should not be using dev_kfree_skb as it is
not irq safe, so instead we should be using dev_kfree_skb_any for freeing
in the dropped path, and dev_consume_skb_any for any frames that were
transmitted.
