iwlwifi: move sysfs_create_group to post request firmware

Move the sysfs_create_group to iwl_ucode_callback after we
have safely got the firmware.

The motivation to do this comes from a warning from lockdep which detected
that we request priv->mutex while holding s_active during a sysfs request
(show_statistics in the example copy pasted). The reverse order exists upon
request_firmware: request_firmware which is a sysfs operation
that requires s_active is run under priv->mutex.

This ensures that we don't get sysfs request before we finish to request
the firmware, avoiding this deadlock.

mac80211: process station blockack action frames from work

Processing an association response could take a bit
of time while we set up the hardware etc. During that
time, the AP might already send a blockack request.
If this happens very quickly on a fairly slow machine,
we can end up processing the blockack request before
the association processing has finished. Since the
blockack processing cannot sleep right now, we also
cannot make it wait in the driver.

As a result, sometimes on slow machines the iwlagn
driver gets totally confused, and no traffic can pass
when the aggregation setup was done before the assoc
setup completed.

I'm working on a proper fix for this, which involves
queuing all blockack category action frames from a
work struct, and also allowing the ampdu_action driver
callback to sleep, which will generally clean up the
code and make things easier.

However, this is a very involved and complex change.
To fix the problem at hand in a way that can also be
backported to stable, I've come up with this patch.
Here, I simply process all aggregation action frames
from the managed interface skb queue, which means
their processing will be serialized with processing
the association response, thereby fixing the problem.

ath9k: Fix rx of mcast/bcast frames in PS mode with auto sleep

The functionality to keep the device awake until it is done with
the rx of any mcast/bcast frames which are pending on AP should
also be added to the hardwares which support auto sleep feature.
This patch fixes frequent failures in ARP resolution when it is
initiated by the other end. Currently auto sleep is enabled only
for ar9003 in ath9k.

ath5k: consistently use rx_bufsize for RX DMA

We should use the same buffer size we set up for DMA also in the hardware
descriptor. Previously we used common->rx_bufsize for setting up the DMA
mapping, but used skb_tailroom(skb) for the size we tell to the hardware in the
descriptor itself. The problem is that skb_tailroom(skb) can give us a larger
value than the size we set up for DMA before. This allows the hardware to write
into memory locations not set up for DMA. In practice this should rarely happen
because all packets should be smaller than the maximum 802.11 packet size.

On the tested platform rx_bufsize is 2528, and we allocated an skb of 2559
bytes length (including padding for cache alignment) but sbk_tailroom() was
2592. Just consistently use rx_bufsize for all RX DMA memory sizes.

Also use the return value of the descriptor setup function.

iwlwifi: fix internal scan race

It is possible for internal scan to race against itself if the device is
not returning the scan results from first requests. What happens in this
case is the cleanup done during the abort of the first internal scan also
cleans up part of the new scan, causing it to access memory it shouldn't.

Here are details:
* First internal scan is triggered and scan command sent to device.
* After seven seconds there is no scan results so the watchdog timer
  triggers a scan abort.
* The scan abort succeeds and a SCAN_COMPLETE_NOTIFICATION is received for
 failed scan.
* During processing of SCAN_COMPLETE_NOTIFICATION we clear STATUS_SCANNING
  and queue the "scan_completed" work.
** At this time, since the problem that caused the internal scan in first
   place is still present, a new internal scan is triggered.
The behavior at this point is a bit different between 2.6.34 and 2.6.35
since 2.6.35 has a lot of this synchronized. The rest of the race
description will thus be generalized.
** As part of preparing for the scan "is_internal_short_scan" is set to
true.
* At this point the completion work for fist scan is run. As part of this
  there is some locking missing around the "is_internal_short_scan"
  variable and it is set to "false".
** Now the second scan runs and it considers itself a real (not internal0
   scan and thus causes problems with wrong memory being accessed.

The fix is twofold.
* Since "is_internal_short_scan" should be protected by mutex, fix this in
  scan completion work so that changes to it can be serialized.
* Do not queue a new internal scan if one is in progress.

net: fix problem in dequeuing from input_pkt_queue

Fix some issues introduced in batch skb dequeuing for input_pkt_queue.
The primary issue it that the queue head must be incremented only
after a packet has been processed, that is only after
__netif_receive_skb has been called.  This is needed for the mechanism
to prevent OOO packet in RFS.  Also when flushing the input_pkt_queue
and process_queue, the process queue should be done first to prevent
OOO packets.

Because the input_pkt_queue has been effectively split into two queues,
the calculation of the tail ptr is no longer correct.  The correct value
would be head+input_pkt_queue->len+process_queue->len.  To avoid
this calculation we added an explict input_queue_tail in softnet_data.
The tail value is simply incremented when queuing to input_pkt_queue.

usb-storage: always print quirks

Right now quirks are printed only when the are manually overriden with
the module parameters. It's not so useful to remind the user that his
parameters are correctly applied; what is useful is to print out the
