Ok... this time for sure. Maybe :) At least its Friday.

[PATCH] create net/wireless/Kconfig and make nl80211 optional
Move the wireless Kconfig options into their own wireless/Kconfig and
add a CONFIG_NL80211 configuration option to allow nl80211
support to be optionally included (default =y)
This also implements stub functions for nl80211_init and nl80211_exit
when CONFIG_NL80211 is not defined.
