>> WARNING: modpost: vmlinux.o(.text+0x1fc2f20): Section mismatch in reference from the function trace_event_raw_event_smc_msg_event() to the variable .init.data:initcall_level_names
The function trace_event_raw_event_smc_msg_event() references
the variable __initdata initcall_level_names.
This is often because trace_event_raw_event_smc_msg_event lacks a __initdata
annotation or the annotation of initcall_level_names is wrong.

Really sorry for the break !

I think its because we missed the '__net_exit' annotation for
smc_sysctl_exit(). I will send a patch to fix this soon
