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.

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

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.

This fixes an incorrect assumption (BUG_ON) made in
cfg80211 when handling country IE regulatory requests.
The assumption was that we won't try to call_crda()
twice for the same event and therefore we will not
recieve two replies through nl80211 for the regulatory
request. As it turns out it is true we don't call_crda()
twice for the same event, however, kobject_uevent_env()
*might* send the udev event twice and/or userspace can
simply process the udev event twice. We remove the BUG_ON()
and simply ignore the duplicate request.

It looks like mac80211 can request the driver to start beaconing with
a beacon interval of zero in some cases (at least for mesh point). This
does not sound correct and something may need to be fixed in
mac80211. However, taken into account the unpleasantness of getting
stuck in an infinite busy loop with rtnl_lock held, let's add a quick
workaround in the driver to avoid the worst symptom while someone more
familiar with the mesh implementation can figure out what should be done
with mac80211 as far as beacon interval configuration is concerned.

When the SME requests to associate to an open AP
ieee80211_sta_set_extra_ie() can be called with zero IE
length. When this happens or when the extra IE has already
been set -EALREADY is passed down and the supplicant will
complain that the operation is already in progress and it will
not let us associate. We correct this by treating -EALREADY
from ieee80211_sta_set_extra_ie() as a success just as we do

I have a TrendNet 652-BRP running OpenWRT + ath9k very well.  The only
problem is that the beacon gets stuck maybe once a day.  After
Vasanthakumar Thiagarajan's "ath9k: cleanup beacon parameters

detected the stuck beacon, and did a reset.  But it would fail the

fully reconfigured after the reset.

I accidentally transposed these in the patch that "fixed" the defaults,
leading to extremely low throughput because of the huge min CW.

Fix printk format for size_t variable:

We were sending the fragmentation threshold value to the wrong table,
causing an LMAC assert when setting it from wext.

When building when CONFIG_IWLWIFI_DEBUG is not set, we get the following
warning:
/work/src/w/drivers/net/wireless/iwlwifi/iwl-core.c: In function ‘iwl_isr’:
/work/src/w/drivers/net/wireless/iwlwifi/iwl-core.c:1707: warning:
unused variable ‘inta_fh’

This patch avoids this warning by adding #ifdef CONFIG_IWLWIFI_DEBUG
before the declaration of inta_fh in iwl_isr() in
drivers/net/wireless/iwlwifi/iwl-core.c

Instead of hardcoding the key length for validation, use the
constants Zhu Yi recently added and add one for AES_CMAC too.

When a scan finishes only the program that asked for it
knows what kind of scan it was; let's tell everybody else
about the scan parameters as well so they can evaluate
the result of the scan better. Also helps with debugging.

We have some validation code in mac80211 but said code will
force an invalid AID to 0 which isn't a valid AID either;
instead require a valid AID (1-2007) to be passed in from
userspace in cfg80211 already. Also move the code before
the race comment since it can only be executed during STA
addition and thus is not racy.

This removes the last usage of beacon_int inside the iee80211_config
structure from rt2x00. The attempt is a bit hackish, and subject to
change in the future when the entire rt2x00_dev structure is
cleaned up and restructured.

Ivo has updated the driver to no longer use the change flag,
so we can remove that, but rt2x00 and ath5k still use the
actual value so let's mark it as deprecated too.

Oddly enough, the firmware's JOIN/START commands don't appear to have
any facility for setting custom IEs, thus the started adhoc network
doesn't advertise its WPA capability in the beacon.  Whee!
