arch/sh/kernel/ftrace.c:130:6: warning: no previous prototype for ‘arch_ftrace_nmi_enter’ [-Wmissing-prototypes] arch/sh/kernel/ftrace.c:140:6: warning: no previous prototype for ‘arch_ftrace_nmi_exit’ [-Wmissing-prototypes] arch/sh/kernel/ftrace.c:316:6: warning: no previous prototype for ‘prepare_ftrace_return’ [-Wmissing-prototypes]
