This patch fix the following error with FUNCTION_GRAPH_TRACER=y:

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 `__irqentry_text_end'

(This patch is need to support function graph tracer of MIPS)
