1479ad4fbf ixgbe: Change the 82599 PHY DSP restart logic
When reprogramming the 82599 analog PHY to either SFI optical or Direct
Attach Twinax, we need to restart the DSP in the PHY.  The current method
can cause contention with our FW which is managing PHY state, and will
cause unexpected link flaps.  This patch fixes the DSP restart by issuing
an AN_RESTART in the MAC, which will properly propagate the DSP restart to
the PHY.  This ensures we don't collide with the FW.

ee5006a19c iwl3945/iwlwifi: fix led bug when SW rfkill
Patch fixes the bug at
http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1903

when SW rfkill is invoked by 'iwconfig txpower off',
the existing connection disassociates and led off command is sent
to the device which returns error as rfkill is 'true'.

Patch fixes this by just avoiding sending the led off/on command when
disassociated. The main purpose of the led_disassociate callback
is to start or stop the blinking.
There are three states in led
1) Always on when radio is on
2) Always off when radio is off
3) blink when associated and if there is some traffic.

In this callback 'allow_blinking' needs to be set false
when associated, as LED will be always on.

c722c625db tun: Only wake up writers
When I added socket accounting to tun I inadvertently introduced
spurious wake-up events that kills qemu performance.  The problem
occurs when qemu polls on the tun fd for read, and then transmits
packets.  For each packet transmitted, we will wake up qemu even
if it only cares about read events.

Now this affects all sockets, but it is only a new problem for
tun.  So this patch tries to fix it for tun first and we can then
look at the problem in general.

278b2513f7 gso: Stop fraglists from escaping
As it stands skb fraglists can get past the check in dev_queue_xmit
if the skb is marked as GSO.  In particular, if the packet doesn't
have the proper checksums for GSO, but can otherwise be handled by
the underlying device, we will not perform the fraglist check on it
at all.

If the underlying device cannot handle fraglists, then this will
break.

The fix is as simple as moving the fraglist check from the device
check into skb_gso_ok.

This has caused crashes with Xen when used together with GRO which
can generate GSO packets with fraglists.

2ec2c68c11 rfkill: always init poll delayed work
The rfkill core didn't initialise the poll delayed work
because it assumed that polling was always done by specifying
the poll function. cfg80211, however, would like to start
polling only later, which is a valid use case and easy to
support, so change rfkill to always initialise the poll
delayed work and thus allow starting polling by calling the
rfkill_resume_polling() function after registration.

c64fb01627 rfkill: create useful userspace interface
The new code added by this patch will make rfkill create
a misc character device /dev/rfkill that userspace can use
to control rfkill soft blocks and get status of devices as
well as events when the status changes.

Using it is very simple -- when you open it you can read
a number of times to get the initial state, and every
further read blocks (you can poll) on getting the next
event from the kernel. The same structure you read is
also used when writing to it to change the soft block of
a given device, all devices of a given type, or all
devices.

This also makes CONFIG_RFKILL_INPUT selectable again in
order to be able to test without it present since its
functionality can now be replaced by userspace entirely
and distros and users may not want the input part of
rfkill interfering with their userspace code. We will
also write a userspace daemon to handle all that and
consequently add the input code to the feature removal
schedule.

In order to have rfkilld support both kernels with and
without CONFIG_RFKILL_INPUT (or new kernels after its
eventual removal) we also add an ioctl (that only exists
if rfkill-input is present) to disable rfkill-input.
It is not very efficient, but at least gives the correct
behaviour in all cases.

19d337dff9 rfkill: rewrite
This patch completely rewrites the rfkill core to address
the following deficiencies:

 * all rfkill drivers need to implement polling where necessary
   rather than having one central implementation

 * updating the rfkill state cannot be done from arbitrary
   contexts, forcing drivers to use schedule_work and requiring
   lots of code

 * rfkill drivers need to keep track of soft/hard blocked
   internally -- the core should do this

 * the rfkill API has many unexpected quirks, for example being
   asymmetric wrt. alloc/free and register/unregister

 * rfkill can call back into a driver from within a function the
   driver called -- this is prone to deadlocks and generally
   should be avoided

 * rfkill-input pointlessly is a separate module

 * drivers need to #ifdef rfkill functions (unless they want to
   depend on or select RFKILL) -- rfkill should provide inlines
   that do nothing if it isn't compiled in

 * the rfkill structure is not opaque -- drivers need to initialise
   it correctly (lots of sanity checking code required) -- instead
   force drivers to pass the right variables to rfkill_alloc()

 * the documentation is hard to read because it always assumes the
   reader is completely clueless and contains way TOO MANY CAPS

 * the rfkill code needlessly uses a lot of locks and atomic
   operations in locked sections

 * fix LED trigger to actually change the LED when the radio state
   changes -- this wasn't done before

6bc61f4d8e libertas: improve function init/shutdown handling for SD8688
This patch is to incorporate Dan Williams' comments for commit:
"libertas: implement function init/shutdown commands for SD8688"

1. remove fn_init_required and fn_shutdown_required variables from
lbs_private structure. If required, __lbs_cmd() will be called
directly to send function init/shutdown command for SD8688 in
if_sdio_probe() or if_sdio_remove() callback.

2. add global variable "user_rmmod" to distinguish between the module
removal case and the card removal case. This flag will be checked in
if_sdio_remove() against SD8688 card to determine whether or not the
function shutdown command needs to be sent.

3. remove "card" from if_sdio_model structure as it cannot store
card pointers for multiple cards. Besides, it's no longer needed
to store the "card" pointer with changes #1 & #2 above.

328d84fb36 wireless/p54: prepare for FIRMWARE_NAME_MAX removal
We're going to remove the FIRMWARE_NAME_MAX definition in order to avoid any
firmware name length restriction.
This patch gets rid of the statically allocated p54usb firmware string, and
replaces them with const char pointers.

iwmc3200wifi: trim down calibration firmware name

The patch trims down iwmc3200wifi calibration firmware name from
iwmc3200wifi-lmac-calib-sdio.bin to iwmc3200wifi-calib-sdio.bin. We can
shorten the firmware name because all calibration is done by LMAC.

6d7db193f2 ar9170: cancel led worker properly on exit
"[PATCH 3/4 v2] ar9170: fix LED power state handling" revealed
a bug which can cause a ugly crash.

The delayed worker is canceled before the LED class functions are
unregistered... So, if something manages to update the LEDs
while unregister routine is running the timer could fire _after_ the
module has been unloaded.

66d008139c ar9170usb: more minor fixes
This patch contains a few more mostly random fixes for the USB front-end.

1. handle irq command response, instead of printing it to the console.

2. remove fixed FIXME.
    (real fix: "ar9170usb: reset device on resume". )

3. some more one-liner.
	- get rid of a useless "return;"
	- add a few branch prediction hints in hot-paths
	etc.

b55d6bcf9b ar9170: fix lockdep warning on hibernate
This patch takes care of Johannes' deadlock report by moving the
mutex_lock right after cancel_work_sync in ar9170_op_stop.

Besides, the janitor does not need to hold the mutex anymore,
so this extra lines can be removed as well.
