I am placing the intel specific file in:
arch/x86/kernel/trace_osnoise.c
and the kernel/trace/trace_osnoise.h looks like this:
#ifdef CONFIG_X86_LOCAL_APIC
int osnoise_arch_register(void);
int osnoise_arch_unregister(void);
#else /* CONFIG_X86_LOCAL_APIC */
#define osnoise_arch_register() do {} while (0)
#define osnoise_arch_unregister() do {} while (0)
#endif /* CONFIG_X86_LOCAL_APIC */
This can be used by other archs as well...
sound reasonable?
