9931df2692 rt2x00: Mark active channel's survey data as "in use"
This is just a cosmetical fix since we only return survey data for the
active channel but it allows iw to show that the survey data is
for the currently used channel.

5d07a3d62f b43legacy: Avoid packet losses in the dma worker code
This patch addresses a bug in the dma worker code that keeps draining
packets even when the hardware queues are full. In such cases packets
can not be passed down to the device and are erroneusly dropped by the
code. It is based on commit bad6919469,
which fixes the same problem in b43.

b015dbc0f9 mwifiex: fix crash during simultaneous scan and connect
If 'iw connect' command is fired when driver is already busy in
serving 'iw scan' command, ssid specific scan operation for connect
is skipped. In this case cmd wait queue handler gets called with no
command in queue (i.e. adapter->cmd_queued = NULL).

This patch adds a NULL check in mwifiex_wait_queue_complete()
routine to fix crash observed during simultaneous scan and assoc
operations.

3aebee028a mwifiex: fix issues in band configuration code
Currently due to following issues in the code even if device is
configured in B only, G only or BG mode using iw bitrates command,
ibss is getting created in BGN mode.

1) mwifiex_channels_to_cfg80211_channel_type() routine gives channel
type as NL80211_CHAN_HT20 for non-HT channel as well, because driver
doesn't store HT information provided by stack for the channel.
This issue is fixed by maintaining channel type information in
'adapter->channel_type'.
2) Band configuration is unnecessarily overwritten with BGN/AN while
setting channel.

This patch makes sure that "adapter->config_bands" correctly gets
modified while setting channel.

106671369e iwlagn: fix (remove) use of PAGE_SIZE
The ICT code erroneously uses PAGE_SIZE. The bug
is that PAGE_SIZE isn't necessarily 4096, so on
such platforms this code will not work correctly
as we'll try to attempt to read an index in the
table that the device never wrote, it always has
4096-byte pages.

Additionally, the manual alignment code here is
unnecessary -- Documentation/DMA-API-HOWTO.txt
states:
  The cpu return address and the DMA bus master address are both
  guaranteed to be aligned to the smallest PAGE_SIZE order which
  is greater than or equal to the requested size.  This invariant
  exists (for example) to guarantee that if you allocate a chunk
  which is smaller than or equal to 64 kilobytes, the extent of the
  buffer you receive will not cross a 64K boundary.

Just use appropriate new constants and get rid of
the alignment code.

While I've not found a smoking gun, there are two places that raised red flags
for me.  The first is in _internal_start_scan, when we queue up a scan; we
first queue the worker, and then set priv->scan_req.  There's theoretically
a 50mS delay which should be plenty, but doing things that way just seems
racy (and not in the good way).

The second is in the scan worker thread itself.  Depending on the state of
priv->scan_channel, we cancel pending scan runs and then requeue a run in
300mS.  We then send the scan command down to the hardware, sleep, and if
we get scan results for all the desired channels, we set priv->scan_req to
NULL.  However, it that's happened in less than 300mS, what happens with
the pending scan run?

This patch addresses both of those concerns.  With the patch applied, we
have not seen the oops in the past two weeks.

ee91d18551 wl12xx: mark no sched scan only after FW event
stop sched scan isn't an immediate operation
and we need to wait for PERIODIC_SCAN_COMPLETE_EVENT_ID
after sending a stop before changing internal state
and notifying upper layers.
Not doing this caused problems when canceling an existing sched
scan and immediately requesting to start a new one
with a different configuration as the FW was still
in the middle of the previous sched scan.

8a30930563 ath9k_hw: make bluetooth coexistence support optional at compile time
Many systems (e.g. embedded systems) do not have wifi modules connected to
bluetooth modules, so bluetooth coexistence is irrelevant there. With the
addition of MCI support, ath9k picked up quite a bit of extra code that
can be compiled out this way.

This patch redefines ATH9K_HW_CAP_MCI and adds an inline wrapper for
querying the bluetooth coexistence scheme, allowing the compiler to
eliminate code that uses it, with only very little use of #ifdef.

On MIPS this reduces the total size for the modules by about 20k.

identical and only need to be handled once. Since there is no way
to turn off one flag from the dongle side, a dummy handler for
function 2 interrupt is placed.

bad6919469 b43: avoid packet losses in the dma worker code.
Following Rafal request, we verified that on "modern" CPUs using one
or more workers is equivalent. Here is patch V3 that addresses the
packet loss bug in the dma engine using only one worker.

-------

This patch addresses a bug in the dma worker code that keeps draining
packets even when the hardware queues are full. In such cases packets
can not be passed down to the device and are erroneusly dropped by the
code.

This problem was already discussed here

http://www.mail-archive.com/b43-dev@lists.infradead.org/msg01413.html

and acknowledged by Michael.

Number of hardware queues is now defined in b43.h (B43_QOS_QUEUE_NUM).

flag representing passive scanning. We should not again compare it
with driver specific macro MWIFIEX_SCAN_TYPE_PASSIVE to determine
