* o Add wmb() in iw_handler_set_spy() for non-coherent archs/cpus
* Based on patch from Pavel Roskin <proski@gnu.org> :
* o Fix kernel data leak to user space in private handler handling
+ *
+ * v7 - 18.3.05 - Jean II
+ * o Remove (struct iw_point *)->pointer from events and streams
+ * o Remove spy_offset from struct iw_handler_def
+ * o Start deprecating dev->get_wireless_stats, output a warning
+ * o If IW_QUAL_DBM is set, show dBm values in /proc/net/wireless
+ * o Don't loose INVALID/DBM flags when clearing UPDATED flags (iwstats)
