[ Upstream commit 9de7695925d5d2d2085681ba935857246eb2817d ]
When both of X86_LOCAL_APIC and X86_THERMAL_VECTOR are disabled, the irq tracing produces a W=1 build warning for the tracing definitions:
In file included from include/trace/trace_events.h:27, from include/trace/define_trace.h:113, from arch/x86/include/asm/trace/irq_vectors.h:383, from arch/x86/kernel/irq.c:29: include/trace/stages/init.h:2:23: error: 'str__irq_vectors__trace_system_name' defined but not used [-Werror=unused-const-variable=]
Make the tracepoints conditional on the same symbosl that guard their usage.
