Merge staging-next tree into Linus's latest version

This required a bit of hand merging due to the conflicts
that happened in the later .34-rc releases, as well as
some staging driver changing coming in through other trees
(v4l and pcmcia).

-	---help---
-	  Aironet makes Arlan, a class of wireless LAN adapters. These use the
-	  www.Telxon.com chip, which is also used on several similar cards.
-	  This driver is tested on the 655 and IC2200 series cards. Look at
-	  <http://www.ylenurme.ee/~elmer/655/> for the latest information.
-
-	  The driver is built as two modules, arlan and arlan-proc. The latter
-	  is the /proc interface and is not needed most of time.
-
-	  On some computers the card ends up in non-valid state after some
-	  time. Use a ping-reset script to clear it.

drivers/staging/batman-adv/CHANGELOG

+batman-adv 0.2.1:
+
+* support latest kernels (2.6.20 - 2.6.33)
+* receive packets directly using skbs, remove old sockets and threads
+* fix various regressions in the vis server
+* don't disable interrupts while sending
+* replace internal logging mechanism with standard kernel logging
+* move vis formats into userland, one general format remains in the kernel
+* allow MAC address to be set, correctly initialize them
+* code refactoring and cleaning for coding style
+* many bugs (null pointers, locking, hash iterators) squashed
