Subject: randconfig build error with next-20140502, in
drivers/net/hyperv/netvsc_drv.c

Building with the attached random configuration file,

drivers/net/hyperv/netvsc_drv.c: In function ‘netvsc_recv_callback’:
drivers/net/hyperv/netvsc_drv.c:648:11: error: ‘struct net_device’ has

make[3]: *** [drivers/net/hyperv/netvsc_drv.o] Error 1

real_num_rx_queues is defined in "include/linux/netdevice.h":
It requires CONFIG_SYSFS flag, which is enabled by default, but not set in 
your config file.

Could you use default config and add hyperv drivers, then try again?

Thanks,
