Johannes Berg 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

This option will enable spectrum measurement for the iwlagn driver.
config IWLWIFI_DEBUG
bool "Enable full debugging output in iwlagn and iwl3945 drivers"
depends on IWLWIFI
---help---
This option will enable debug tracing output for the iwlwifi drivers
This will result in the kernel module being ~100k larger. You can
control which debug output is sent to the kernel log by setting the
value in
/sys/class/net/wlan0/device/debug_level
This entry will only exist if this option is enabled.
To set a value, simply echo an 8-byte hex value to the same file:
% echo 0x43fff > /sys/class/net/wlan0/device/debug_level
You can find the list of debug mask values in:
drivers/net/wireless/iwlwifi/iwl-debug.h
If this is your first time using this driver, you should say Y here
as the debug information can assist others in helping you resolve
any problems you may encounter.

config IWLAGN
tristate "Intel Wireless WiFi Next Gen AGN (iwlagn)"
depends on IWLWIFI
---help---
Select to build the driver supporting the:
Intel Wireless WiFi Link Next-Gen AGN
This driver uses the kernel's mac80211 subsystem.
In order to use this driver, you will need a microcode (uCode)
image for it. You can obtain the microcode from:
<http://intellinuxwireless.org/>.
The microcode is typically installed in /lib/firmware. You can
look in the hotplug script /etc/hotplug/firmware.agent to
determine which directory FIRMWARE_DIR is set to when the script
runs.
If you want to compile the driver as a module ( = code which can be
inserted in and removed from the running kernel whenever you want),
say M here and read <file:Documentation/kbuild/modules.txt>. The
module will be called iwlagn.ko.
