[tom arnall <kloro@xxxxxxx>]

while trying to compile the madwifi driver, i encountered the following error:

make[2]: Entering directory `/usr/src/kernel-headers-2.6.8-2-386'

the offending line - in processor.h  - is:

	extern struct tss_struct init_tss[NR_CPUS];

thanks in advance for your help,
