Compiling without CONFIG_X86_LOCAL_APIC set, apic.c will not be compiled, and the irq tracepoints will not be created via the CREATE_TRACE_POINTS macro. When CONFIG_X86_LOCAL_APIC is not set, we get the following build error: LD init/built-in.o arch/x86/built-in.o: In function `trace_x86_platform_ipi_entry': linux-test.git/arch/x86/include/asm/trace/irq_vectors.h:66: undefined reference to `__tracepoint_x86_platform_ipi_entry' arch/x86/built-in.o: In function `trace_x86_platform_ipi_exit': linux-test.git/arch/x86/include/asm/trace/irq_vectors.h:66: undefined reference to `__tracepoint_x86_platform_ipi_exit' arch/x86/built-in.o: In function `trace_irq_work_entry': linux-test.git/arch/x86/include/asm/trace/irq_vectors.h:72: undefined reference to `__tracepoint_irq_work_entry' arch/x86/built-in.o: In function `trace_irq_work_exit': linux-test.git/arch/x86/include/asm/trace/irq_vectors.h:72: undefined reference to `__tracepoint_irq_work_exit' arch/x86/built-in.o:(__jump_table+0x8): undefined reference to `__tracepoint_x86_platform_ipi_entry' arch/x86/built-in.o:(__jump_table+0x14): undefined reference to `__tracepoint_x86_platform_ipi_exit' arch/x86/built-in.o:(__jump_table+0x20): undefined reference to `__tracepoint_irq_work_entry' arch/x86/built-in.o:(__jump_table+0x2c): undefined reference to `__tracepoint_irq_work_exit' make[1]: *** [vmlinux] Error 1 make: *** [sub-make] Error 2 As irq.c is always compiled for x86, it is a more appropriate location to create the irq tracepoints.
