-What:   CONFIG_WIRELESS_OLD_REGULATORY - old static regulatory information
-When:   March 2010 / desktop catchup
-
-Why:    The old regulatory infrastructure has been replaced with a new one
-        which does not require statically defined regulatory domains. We do
-        not want to keep static regulatory domains in the kernel due to the
-        the dynamic nature of regulatory law and localization. We kept around
-        the old static definitions for the regulatory domains of:
-
-                * US
-                * JP
-                * EU
-
-        and used by default the US when CONFIG_WIRELESS_OLD_REGULATORY was
-        set. We will remove this option once the standard Linux desktop catches
-        up with the new userspace APIs we have implemented.

+---------------------------------------
+
+In most situations the userland solution using CRDA as described
+above is the preferred solution.  However in some cases a set of
+rules built into the kernel itself may be desirable.  To account
+for this situation, a configuration option has been provided
+(i.e. CONFIG_CFG80211_INTERNAL_REGDB).  With this option enabled,
+the wireless database information contained in net/wireless/db.txt is
+used to generate a data structure encoded in net/wireless/regdb.c.
+That option also enables code in net/wireless/reg.c which queries
+the data in regdb.c as an alternative to using CRDA.
+
+The file net/wireless/db.txt should be kept up-to-date with the db.txt
+file available in the git repository here:
+
+    git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-regdb.git
+
+Again, most users in most situations should be using the CRDA package
+provided with their distribution, and in most other situations users
+should be building and using CRDA on their own rather than using
+this option.  If you are not absolutely sure that you should be using
+CONFIG_CFG80211_INTERNAL_REGDB then _DO_NOT_USE_IT_.
