c752c78275 RDMA/cxgb3: Set active_mtu in ib_port_attr
When running ibv_devinfo, the active_mtu returned is garbage.  This is
due to the field not being populated in the query_port function in the

After investigating a JRE failure, I found this bug was introduced a long time

b0dee5784d Fix modpost failure when rx handlers are not inlined.
When CONFIG_MAC80211_MESH=n and CONFIG_MAC80211_NOINLINE=y,
gcc doesn't optimize out a call to ieee80211_rx_h_mesh_fwding,
even if the previous comparison is always false in this case.
This leads to the following errors during modpost:

ERROR: "mpp_path_lookup" [net/mac80211/mac80211.ko] undefined!
ERROR: "mpp_path_add" [net/mac80211/mac80211.ko] undefined!

Fix by removing the possibility of uninlining
ieee80211_rx_h_mesh_fwding rx handler.

4c99f3e4cf rt2x00: Fix build errors due to modularized rfkill or leds and built-in rt2x00.
Fix by disabling rt2x00 rfkill support when rt2x00 is built-in and rfkill has been modularized, and
a similar scheme for the relationship between leds_class and rt2x00..
Also, give a warning to the end-user when rfkill-/leds-support is disabled this way, so that the
end-user has at least some clues on what is going on.

Proper fixing required some general updates of the Kconfig-structure for the rt2x00 driver, whereby
internal configuration symbols had to be moved to after the user-visible configuration symbols.

All of the above have been fixed. One question, however, remains: In struct
bootrec, the array "data" is treated in many places as native CPU order, but
it may be little-endian everywhere. As far as I can tell, this driver has only
been used with little-endian hardware.

943c246e9b IPoIB: Use netif_tx_lock() and get rid of private tx_lock, LLTX
Currently, IPoIB is an LLTX driver that uses its own IRQ-disabling
tx_lock.  Not only do we want to get rid of LLTX, this actually causes
problems because of the skb_orphan() done with this tx_lock held: some
skb destructors expect to be run with interrupts enabled.

The simplest fix for this is to get rid of the driver-private tx_lock
and stop using LLTX.  We kill off priv->tx_lock and use
netif_tx_lock[_bh]() instead; the patch to do this is a tiny bit
tricky because we need to update places that take priv->lock inside
the tx_lock to disable IRQs, rather than relying on tx_lock having
already disabled IRQs.

Also, there are a couple of places where we need to disable BHs to
make sure we have a consistent context to call netif_tx_lock() (since
we no longer can use _irqsave() variants), and we also have to change
ipoib_send_comp_handler() to call drain_tx_cq() through a timer rather
than directly, because ipoib_send_comp_handler() runs in interrupt
context and drain_tx_cq() must run in BH context so it can call
netif_tx_lock().

64b9e0294d sched: minor optimizations in wake_affine and select_task_rq_fair
This patch does following:
o Removes unused variable and argument "rq".
o Optimizes one of the "if" conditions in wake_affine() - i.e.  if
  "balanced" is true, we need not do rest of the calculations in the
  condition.
o If this cpu is same as the previous cpu (on which woken up task
  was running when it went to sleep), no need to call wake_affine at all.

ba0166708e sctp: Fix kernel panic while process protocol violation parameter
Since call to function sctp_sf_abort_violation() need paramter 'arg' with
'struct sctp_chunk' type, it will read the chunk type and chunk length from
the chunk_hdr member of chunk. But call to sctp_sf_violation_paramlen()
always with 'struct sctp_paramhdr' type's parameter, it will be passed to
sctp_sf_abort_violation(). This may cause kernel panic.

   sctp_sf_violation_paramlen()
     |-- sctp_sf_abort_violation()
        |-- sctp_make_abort_violation()

This patch fixed this problem. This patch also fix two place which called
sctp_sf_violation_paramlen() with wrong paramter type.

24918b61b5 ALSA: hda - Fix model for Dell Inspiron 1525
Dell Inspiron 1525 seems to have a buggy BIOS setup and screws up
the recent codec parser, as reported by Oleksandr Natalenko:
    http://lkml.org/lkml/2008/9/12/203

This patch adds the working model, dell-3stack, statically.

e3145dfb7b ALSA: ASoC: Fix cs4270 error path
The error path in cs4270_probe/cs4270_remove is pretty broken:
* If cs4270_probe fails, codec is leaked.
* If snd_soc_register_card fails, cs4270_i2c_driver stays registered.
* If I2C support is enabled but no I2C device is found, i2c_del_driver
  is never called (neither in cs4270_probe nor in cs4270_remove.

Fix all 3 problems by implementing a clean error path in cs4270_probe
and jumping to its labels as needed.
