This solves the first build failure but there's still a second build 
failure:

 drivers/net/cnic.c: In function ‘init_bnx2_cnic’:
 drivers/net/cnic.c:2520: error: implicit declaration of function ‘__symbol_get’
 drivers/net/cnic.c:2520: warning: assignment makes pointer from integer without a cast
 make[1]: *** [drivers/net/cnic.o] Error 1
 make: *** [drivers/net/cnic.o] Error 2

This too triggers with the config i sent. The patch below solves it 
- but i havent done more testing.
