And once this is fixed, new problems crop up :-)

WARNING: net/ipv6/ipv6.o - Section mismatch: reference to .exit.text:fib6_rules_cleanup from .text between 'ip6_route_cleanup' (at offset 0xbfd4) and 'rt6_mtu_change_route'
WARNING: "fib_rules_dump" [net/ipv6/ipv6.ko] undefined!
WARNING: "fib_rules_register" [net/ipv6/ipv6.ko] undefined!
WARNING: "fib_rules_lookup" [net/ipv6/ipv6.ko] undefined!
WARNING: "fib_rules_unregister" [net/ipv6/ipv6.ko] undefined!

The fib_rules_* cases are easy to fix, simply export
those symbols using EXPORT_SYMBOL_GPL() in net/core/fib_rules.c

The other problem is a bit more onerous.  ip6_route_cleanup is not
marked __exit, since it is called from initialization as well as
exit contexts.  Therefore fib6_rules_cleanup() has to have it's
__exit marker deleted too.

IPv6 seems to build modular now with all of these issues taken
care of.  Thomas, please integrate these fixes into your patch.

Thanks.
