fd3065b25b chelsio: remove get_clock and use ktime_get
The get_clock() of the chelsio driver clashes with the s390 one.
The chelsio helper reads a timespec via ktime just to convert it
back to ktime. I can see no different outcome from calling
ktime_get directly.

Remove the get_clock and use ktime_get directly.

c63da990cd bnx2x: Prevent link flaps when booting from SAN.
It is possible that the driver is configured to operate with a certain
link configuration which differs from the link's configuration during
boot from SAN - this would cause the driver to flap the link.

Said flap may be missed by specific switches, causing dcbx convergence
to be too long and boot sequence to fail. Convergence is longer because
switch ignores new dcbx packets due to counters mismatch, as only host
side reset the counters due to the link flap.

This patch causes the driver to ignore user's initial configuration during
boot from SAN, and continues with the existing link configuration.

If a SMSC PHY is in this mode in the config_init

c8a8ab4472 iwlwifi: change TX code to suppress smatch warning
By using a few temporary variables, smatch can track

beyond the tid_data array.

This also makes the generated code a bit smaller, so
it's a win all around.

cb6d0f5eef ixgbe: check whether thermal sensor is enabled.
The X540's internal thermal sensor should not be enabled for all devices, but
only those devices which enable it in the NVM image. It is expected that
actively cooled devices will have it enabled, but passively cooled devices might
not want it enabled. This is due to passively cooled devices operating very near
the thermal threshold, sometimes within the margin of error of the thermal
sensor. Thus these devices may not be good candidates for using the thermal
sensor.

This patch uses the enabled bit in the FWSM register to check whether we should
be enabling the thermal sensor, and only sets the THERMAL_SENSOR_CAPABLE flag
for those devices which have it enabled.

f5685ba675 rt2x00: Only specify interface combinations if more then one interface is possible
Otherwise rt2500* triggers a warning in cfg80211, from net/wireless/core.c:

	/* Combinations with just one interface aren't real */
	if (WARN_ON(c->max_interfaces < 2))

This was introduced in commit 55d2e9da74:
rt2x00: Replace open coded interface checking with interface combinations.

1981e881fd carl9170: explain why sta cannot be NULL for ampdus
Dan Carpenter reported that smatch detected a potential
problem with the code [1]:
 drivers/net/wireless/ath/carl9170/tx.c:1488 carl9170_op_tx()
  error: we previously assumed 'sta' could be null (see line 1482)

 drivers/net/wireless/ath/carl9170/tx.c
  1482  if (sta) {
           ^^^^^ New check.
  [...]
  1485  }
  1487  if (info->flags & IEEE80211_TX_CTL_AMPDU) {
  1488    run = carl9170_tx_ampdu_queue(ar, sta, skb);
                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   Old dereference of "sta" inside the call to carl9170_tx_ampdu_queue().

A range of solutions have been discussed in [2] and
we agreed on the following: "
> we might as well add a comment to carl9170_tx_ampdu_queue
> and explain the situation [in a way that's obvious to a
> human reader]. This way we can save the "if"... which is
> a small win since carl9170_op_tx is sort of a hot-path.
Putting a comment there is fine. Without the comment
it's easy for a human reader to get confused why the
check is there. So long as humans can read the code,
that's all that matters."

This is an NFC LLCP fix for 3.7 and contains only one patch.

It fixes a potential crash when receiving an LLCP HDLC frame acking a frame
that is not the last sent one. In that case we may dereference an already
freed pointer.

01331040e6 wireless: fix VHT max AMPDU exponent definition
This is really a 3-bit field, not a single bit,
so declare a mask and shift. Also fix hwsim, it
advertises the maximum possible.

While at it reindent all the defines using tabs
instead of spaces.

0d650ec75a cnic: Fix rare race condition during iSCSI disconnect.
If the initiator and target try to close the connection at about the same
time, there is a race condition in the termination sequence for bnx2x.
Fix the problem by waiting for the remote termination to complete before
deleting the Connection ID.  This will prevent the firmware assert.

Update version to 2.5.15.
