I am seeing build errors when CONFIG_SYSCTL is not set:

ld: net/ipv4/ip_tunnel.o: in function `ip_tunnel_init_net':
ip_tunnel.c:(.text+0x2ea0): undefined reference to `sysctl_fb_tunnels_only_for_init_net'

due to 316cdaa1158af:

    net: add option to not create fall-back tunnels in root-ns as well


This was first reported to netdev@ on Sept. 02 but Mahesh was not cc-ed
on that report.
