All warnings (new ones prefixed by >>, old ones prefixed by <<):

>> WARNING: modpost: vmlinux.o(.text+0x1c35db0): Section mismatch in reference from the function tipc_topsrv_init_net() to the variable .init.text:.L0
The function tipc_topsrv_init_net() references
the variable __init .L0 .
This is often because tipc_topsrv_init_net lacks a __init
annotation or the annotation of .L0 is wrong.
