Compiling iwlwifi or alx against 3.4.47 kernel gives redefinition error. Tried using compat-drivers-3.9-rc4-2-su, compat-drivers-3.9-rc2-2-su, and compat-drivers-3.8.3-2-snpu. Does not work from any of them.

Patch against compat-drivers-3.9-rc4-2-su follows body.

I've tried 3.10.4-1 as well as the latest development release (20130802), and had this issue with kernel 3.6.10 in Fedora 18. I did not have this issue however in Fedora 19 with kernel 3.9.5
