This broke earlier patch 
b872a2371ffd13e6d83423ef621a707df4c158ac "udp_diag: Make it module when ipv6 is a module",
which brings back the compilation error when compiling linus master (v3.3-rc2+):

net/built-in.o: In function `udp_dump_one':
udp_diag.c:(.text+0x59852): undefined reference to `__udp6_lib_lookup'
