Hey,

About the second issue - seems the following patch is missing from your tree:
http://permalink.gmane.org/gmane.linux.kernel.wireless.general/105449

So the warning is bogus. It will happen if you're working on a single
processor (UP) system.

To get the latest driver, you can use Luca's tree, which already
contains this patch:
git://git.kernel.org/pub/scm/linux/kernel/git/luca/wl12xx.git
