[PATCH v10 tip 3/9] tracing: attach BPF programs to kprobes

User interface: struct perf_event_attr attr = {.type = PERF_TYPE_TRACEPOINT, .config = event_id, ...}; event_fd = perf_event_open(&attr,...); ioctl(event_fd, PERF_EVENT_IOC_SET_BPF, prog_fd); prog_fd is a file descriptor associated with BPF program previously loaded. event_id is an ID of created
