Hi Solomon,
I just compile tested cw1200 against many kernel versions and I always
get an error of a missing symbol for kernel <= 3.9:

I deactivate compiling against older kernels than 3.6.39 because that
caused some other problems like starting with 3.6.37 and missing
hw_features in 2.6.38:
drivers/net/wireless/cw1200/bh.c: In function ‘cw1200_register_bh’:
drivers/net/wireless/cw1200/bh.c:62:72: error: ‘WQ_CPU_INTENSIVE’
undeclared (first use in this function)
drivers/net/wireless/cw1200/bh.c:62:72: note: each undeclared
identifier is reported only once for each function it appears in
make[7]: *** [/drivers/net/wireless/cw1200/bh.o] Error 1
