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

<< WARNING: modpost: vmlinux.o(.text.unlikely+0x4c10): Section mismatch in reference from the function __trace_event_discard_commit() to the variable .init.data:initcall_level_names
>> WARNING: modpost: vmlinux.o(.text.unlikely+0x4f50): Section mismatch in reference from the function trace_define_generic_fields() to the variable .init.data:initcall_level_names
The function trace_define_generic_fields() references
the variable __initdata initcall_level_names.
This is often because trace_define_generic_fields lacks a __initdata
annotation or the annotation of initcall_level_names is wrong.
