I think David's patch missed kernel/trace/trace_export.c
struct ftrace_event_call __used \
__attribute__((__aligned__(4))) \
__attribute__((section("_ftrace_events"))) event_##call = { \
and kernel/trace/trace.h:
#define FTRACE_ENTRY(call, struct_name, id, tstruct, print) \
extern struct ftrace_event_call \
__attribute__((__aligned__(4))) event_##call;
does it help if you remove these ?
