I manually applied these 9 to wireless-next:

4b478bf6bdd8 wifi: libertas: drop 16-bit PCMCIA support
77e49bec6414 wifi: atmel: remove wext style at76c50x drivers
6853c70ba5ed wifi: remove orphaned cisco/aironet driver
d0172d5f7576 wifi: remove obsolete hostap driver
757a46c2a7a9 wifi: remove orphaned zd1201 driver
1535d5962d79 wifi: remove orphaned orinoco driver
6b9dbaff83d6 wifi: remove orphaned ray_cs driver
238349207cd3 wifi: remove orphaned wl3501 driver
bec95598b24a wifi: remove orphaned rndis_wlan driver

I dropped this patch as we got several reports about people using the
driver:

[RFC] wifi: remove ipw2100/ipw2200 drivers

The patches are queued for v6.8. Arnd, thanks a lot for cleaning this
up!
