327967cba4 ath9k: Cleanup add/change_interface callbacks
*Remove all the checks that will be handled by cfg80211
based on the interface combination advertised. For instance,
driver supports at the maximum 8 beaconing interface, while
we advertise maximum 8 beaconing interface in the interface
combination support.

*cfg80211 will take care of not allowing
us to add an interface that is not supported by the
driver, further if the change_interface changes the
old interface to a beaconing interface while we had
reached the max limit of 8 beaconing interface, again
cfg80211 takes care of this stuff!
So remove all these checks.

*Beautify placing PS wrappers in the appropriate
position.

af2c8ffe56 brcm80211: Remove bogus memcpy in ai_detach
gcc 4.8 warns for this memcpy. While the copy size is correct, the whole

there's no need to use memcpy to copy pointers anyways. And the
type of the pointer was wrong, but at least those are always the same.

Just remove it.

75c5da279e drm/i915: fix up the IBX transcoder B check
This has been added in

commit de9a35abb3
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Tue Jun 5 11:03:40 2012 +0200

    drm/i915: assert that the IBX port transcoder select w/a is implemented

Unfortunately I've failed to notice that these checks are not just
called for the port that is about to be disabled, but for all (which
makes sense for an assert ...), and the WARN missfired when disabling
another pipe than the one with the dp port.

Hence also check whether the port is actually disabled.

c302d6133c ALSA: hda_intel: add position_fix quirk for Asus K53E
Commit c20c5a841c changed some chipsets to
default to POS_FIX_COMBO so they now use POS_FIX_LPIB instead of
POS_FIX_POSBUF. Since then I've been getting artifacts on playback, including
repeated sounds on my Asus laptop.

My hardware is Cougar Point which the commit log of
c20c5a841c mentions as tested so POS_FIX_COMBO
probably works in general but apparently it doesn't on Asus K53E therefore the
need for the quirk.

O_RDONLY is zero so the original test (f->f_flags & O_RDONLY) is always
false and it will never do compress capture.  The test for O_WRONLY is
also slightly off.  The original test would consider "->flags =
(O_WRONLY | O_RDWR)" as write only instead of rejecting it as invalid.

I've also removed the pr_err() because that could flood dmesg.

Currently SSI driver only supports slave mode and only need to handle

9b2f4cb65f crypto: authenc - Fix crash with zero-length assoc data
The authenc code doesn't deal with zero-length associated data
correctly and ends up constructing a zero-length sg entry which
causes a crash when it's fed into the crypto system.

This patch fixes this by avoiding the code-path that triggers
the SG construction if we have no associated data.

This isn't the most optimal fix as it means that we'll end up
using the fallback code-path even when we could still execute
the digest function.  However, this isn't a big deal as nobody
but the test path would supply zero-length associated data.

6895f97e15 kbuild: add symbol prefix arg to kallsyms
Commit 1f2bfbd00e ("kbuild: link of
vmlinux moved to a script") introduced in v3.5-rc1 broke kallsyms on
architectures which have symbol prefixes.

The --symbol-prefix argument used to be added to the KALLSYMS command
line from the architecture Makefile, however this isn't picked up by the
new scripts/link-vmlinux.sh. This resulted in symbols like
kallsyms_addresses being added which weren't correctly overriding the
weak symbols such as _kallsyms_addresses. These could then trigger
BUG_ONs in kallsyms code.

This is fixed by removing the KALLSYMS addition from the architecture
Makefile, and using CONFIG_SYMBOL_PREFIX in the link-vmlinux.sh script
to determine whether to add the --symbol-prefix argument.

3d037774b4 EHCI: Update qTD next pointer in QH overlay region during unlink
There is a possibility of QH overlay region having reference to a stale
qTD pointer during unlink.

Consider an endpoint having two pending qTD before unlink process begins.
The endpoint's QH queue looks like this.

qTD1 --> qTD2 --> Dummy

To unlink qTD2, QH is removed from asynchronous list and Asynchronous
Advance Doorbell is programmed.  The qTD1's next qTD pointer is set to
qTD2'2 next qTD pointer and qTD2 is retired upon controller's doorbell
interrupt.  If QH's current qTD pointer points to qTD1, transfer overlay
region still have reference to qTD2. But qtD2 is just unlinked and freed.
This may cause EHCI system error.  Fix this by updating qTD next pointer
in QH overlay region with the qTD next pointer of the current qTD.

ec4010ecc2 bnx2x: EEE code refactoring
In order to lay the foundation for 1G EEE support, several segments of code
which are common to both 1G and 10G EEE configurations were extracted from
the 10G EEE configuration flow to their own functions.
E.g., bnx2x_eee_initial_config, bnx2x_eee_advertise, bnx2x_eee_disable, etc.

The rest of the EEE functions were relocated and placed in a single,
continuous section of the file.

08e9acc25a bnx2x: EEE status is read locally
This patch aligns the EEE status with that of all other link properties,
by changing the way its accessed - instead of a direct read to the shared
memory, each function maintain its own copy locally.

0b836ddde1 ixp4xx_hss: fix build failure due to missing linux/module.h inclusion
Commit 36a1211970 (netprio_cgroup.h:
dont include module.h from other includes) made the following build
error on ixp4xx_hss pop up:

  CC [M]  drivers/net/wan/ixp4xx_hss.o
 drivers/net/wan/ixp4xx_hss.c:1412:20: error: expected ';', ',' or ')'
 before string constant
 drivers/net/wan/ixp4xx_hss.c:1413:25: error: expected ';', ',' or ')'
 before string constant
 drivers/net/wan/ixp4xx_hss.c:1414:21: error: expected ';', ',' or ')'
 before string constant
 drivers/net/wan/ixp4xx_hss.c:1415:19: error: expected ';', ',' or ')'
 before string constant
 make[8]: *** [drivers/net/wan/ixp4xx_hss.o] Error 1

This was previously hidden because ixp4xx_hss includes linux/hdlc.h which
includes linux/netdevice.h which includes linux/netprio_cgroup.h which
used to include linux/module.h. The real issue was actually present since
the initial commit that added this driver since it uses macros from
linux/module.h without including this file.

6d57e9078e etherdevice: introduce help function eth_zero_addr()
a lot of code has either the memset or an inefficient copy
from a static array that contains the all-zeros Ethernet address.
Introduce help function eth_zero_addr() to fill an address with
all zeros, making the code clearer and allowing us to get rid of
some constant arrays.
