commit 0866b03c7d upstream.
If b43 or b43legacy are deauthenticated or disconnected, there is a
possibility that a reconnection is tried with the queues stopped in
mac80211. To prevent this, start the queues before setting
STAT_INITIALIZED.
In b43, a similar change has been in place (twice) in the
wireless_core_init() routine. Remove the duplicate and add similar
code to b43legacy.

commit 7bfbae10dc upstream.
While ath9k does not support RIFS yet, the ability to receive RIFS
frames is currently enabled for most chipsets in the initvals.
This is causing baseband related issues on AR9160 and AR9130 based
chipsets, which can lock up under certain conditions.
This patch fixes these issues by overriding the initvals, effectively
disabling RIFS for all affected chipsets.

commit 5c0ba62fd4 upstream.
When selecting the tx fallback rate, rc.c used a separate variable
'nrix' for storing the next rate index, however it did not use that as
reference for further rate index lowering. Because of that, it ended up
reusing the same rate for multiple multi-rate retry stages, thus
decreasing delivery probability under changing link conditions.
This patch removes the separate (unnecessary) variable and fixes
fallback the way it was intended to work.
This should result in increased throughput and better link stability.

commit d8728ee919 upstream.
In AP mode, ath_beacon_config_ap only restarts the timer if a TSF
restart is requested. Apparently this was added, because this function
unconditionally sets the flag for TSF reset.
The problem with this is, that ath9k_hw_reset() clobbers the timer
registers (specified in the initvals), thus effectively disabling the
SWBA interrupt whenever a card reset without TSF reset is issued
(happens in a few places in the code).
This patch fixes ath_beacon_config_ap to only issue the TSF reset flag
when necessary, but reinitialize the timer unconditionally. Tests show,
that this is enough to keep the SWBA interrupt going after a call to
ath_reset()

commit 14acdde6e5 upstream.
The newer single chip hardware family of chipsets have not been
experiencing issues with power saving set by default with recent
fixes merged (even into stable). The remaining issues are only
reported with AR5416 and since enabling PS by default can increase
power savings considerably best to take advantage of that feature
as this has been tested properly.
For more details on this issue see the bug report:
http://bugzilla.kernel.org/show_bug.cgi?id=14267
We leave AR5416 with PS disabled by default, that seems to require

commit da3f5cf1f8 upstream.
The alignment requirement for 64-bit load/store instructions on ARM is
implementation defined. Some CPUs (such as Marvell Feroceon) do not
generate an exception, if such an instruction is executed with an
address that is not 64 bit aligned. In such a case, the Feroceon
corrupts adjacent memory, which showed up in my tests as a crash in the
rx path of ath9k that only occured with CONFIG_XFRM set.
This crash happened, because the first field of the mac80211 rx status
info in the cb is an u64, and changing it corrupted the skb->sp field.
This patch also closes some potential pre-existing holes in the sk_buff
struct surrounding the cb[] area.

commit a8a5164c29 upstream.
The cs5535-gpio driver's get() function was returning the output value.
This means that the GPIO pins would never work as an input, even if
configured as an input.
The driver should return the READ_BACK value, which is the sensed line
value. To make that work when the direction is 'output', INPUT_ENABLE
needs to be set.
In addition, the driver was not disabling OUTPUT_ENABLE when the direction
is set to 'input'. That would cause the GPIO to continue to drive the pin
if the direction was ever set to output.
This issue was noticed when attempting to use the gpiolib driver to read
an external input. I had previously been using the char/cs5535-gpio
driver.

conditions into the code.
The problem case is TTY_DRIVER_RESET_TERMIOS = 0. In that case while we
abort the ldisc change, the hangup processing has not cleaned up and restarted
the ldisc either.
We can't restart the ldisc stuff in the set_ldisc as we don't know what
the hangup did and may touch stuff we shouldn't as we are no longer
supposed to influence the tty at that point in case it has been re-opened
before we get rescheduled.
Instead do it the simple way. Always re-init the ldisc on the hangup, but
use TTY_DRIVER_RESET_TERMIOS to indicate that we should force N_TTY.

The problem is that kobject_add_internal() first adds a kobject to the
kset and then try to create sysfs directory for it. If the creation
fails, it remove the kobject from the kset. get_device_parent()
accesses class_dirs kset while only holding class_dirs.list_lock to
see whether the cuse class dir exists. But when it exists, it may not
have finished initialization yet or may fail and get removed soon. In
the above case, the former happened so the second one ends up trying
to create subdirectory under NULL sysfs_dirent.
Fix it by grabbing a mutex in get_device_parent().

commit 86c38a31aa upstream.
GCC 4.5 introduces behavior that forces the alignment of structures to
use the largest possible value. The default value is 32 bytes, so if
some structures are defined with a 4-byte alignment and others aren't
declared with an alignment constraint at all - it will align at 32-bytes.
For things like the ftrace events, this results in a non-standard array.
When initializing the ftrace subsystem, we traverse the _ftrace_events
section and call the initialization callback for each event. When the
structures are misaligned, we could be treating another part of the
structure (or the zeroed out space between them) as a function pointer.
This patch forces the alignment for all the ftrace_event_call structures
to 4 bytes.
Without this patch, the kernel fails to boot very early when built with
gcc 4.5.
It's trivial to check the alignment of the members of the array, so it
might be worthwhile to add something to the build system to do that
automatically. Unfortunately, that only covers this case. I've asked one
of the gcc developers about adding a warning when this condition is seen.

There was a bug in the old period code that caused intel_pmu_enable_all()

In staring at that code it made my head hurt, so I rewrote it in a
hopefully simpler fashion. Its now fully symetric between tick and
overflow driven adjustments and uses less data to boot.
The only complication is that it basically wants to do a u128 division.
The code approximates that in a rather simple truncate until it fits
fashion, taking care to balance the terms while truncating.
This version does not generate that sampling artefact.

commit 33a470f6d5 upstream.
Looking at drivers/macintosh/therm_adt746x.c, the sysfs files are
created in thermostat_init() and removed in thermostat_exit(), which
are the driver's init and exit functions. These files are backed-up by
a per-device structure, so it looks like the wrong thing to do: the
sysfs files have a lifetime longer than the data structure that is
backing it up.
I think that sysfs files creation should be moved to the end of
probe_thermostat() and sysfs files removal should be moved to the
beginning of remove_thermostat().

commit a9c9b4429d upstream.
The hibernate memory preallocation code allocates memory to push some
user space data out of physical RAM, so that the hibernation image is
not too large. It allocates more memory than necessary for creating
the image, so it has to release some pages to make room for
allocations made while suspending devices and disabling nonboot CPUs,
or the system will hang due to the lack of free pages to allocate
from. Unfortunately, the function used for freeing these pages,
free_unnecessary_pages(), contains a bug that prevents it from doing
the job on all systems without highmem.
Fix this problem, which is a regression from the 2.6.30 kernel, by
using the right condition for the termination of the loop in
free_unnecessary_pages().

commit 29e1fa3565 upstream.
ULE (Unidirectional Lightweight Encapsulation RFC 4326) decapsulation
has a bug that causes endless loop when Payload Pointer of MPEG2-TS
frame is 182 or 183. Anyone who sends malicious MPEG2-TS frame will
cause the receiver of ULE SNDU to go into endless loop.
This patch was generated and tested against linux-2.6.32.9 and should
apply cleanly to linux-2.6.33 as well because there was only one typo
fix to dvb_net.c since v2.6.32.
This bug was brought to you by modern day Santa Claus who decided to
shower the satellite dish at Keio University with heavy snow causing
huge burst of errors. We, receiver end, received Santa Claus's gift in
the form of kernel bug.
Care has been taken not to introduce more bug by fixing this bug, but
please scrutinize the code for I always produces buggy code.

commit e37bcc0de0 upstream.
It turns out that Mimio has a userspace solution for this product using
libusb, and the in-kernel driver is just getting in the way now and
causing problems. So they have asked that the in-kernel driver be
removed. As the staging driver wasn't quite working anyway, and Mimio
supports their libusb solution for all distros, I am removing the
in-kernel driver.
The libusb solution can be downloaded from:

commit 8a8e29752d upstream.
Without WEXT_PRIV set the p80211wext.c fails to build due to unknown fields in
the iw_handler_def struct.
Those fields are enclosed in WEXT_PRIV conditionals in the prototype
of iw_handler_def in include/net/iw_handler.h
