kernel/built-in.o: In function `print_graph_irq':
trace_functions_graph.c:(.text+0x6dba0): undefined reference to 
`__irqentry_text_start'
trace_functions_graph.c:(.text+0x6dba8): undefined reference to 
`__irqentry_text_start'
trace_functions_graph.c:(.text+0x6dbd0): undefined reference to 
`__irqentry_text_end'
trace_functions_graph.c:(.text+0x6dbd4): undefined reference to
