返回类型：void

参数：

类型参数名称
struct trace_array *tr
struct trace_array_cpu *data
struct mmiotrace_map *map
329  call等于event_mmiotrace_map
330  buffer等于buffer
333  pc等于抢占计数值
335  event等于trace_buffer_lock_reserve(buffer, TRACE_MMIO_MAP, entry的长度, 0, pc)
337  如果非event则
338  atomic_inc( & dropped_count)
339  返回
341  entry等于g_buffer_event_data - return the data of the event*@event: the event to get the data from
342  map等于map
344  如果非call_filter_check_discard(call, entry, buffer, event)则trace_buffer_unlock_commit(tr, buffer, event, 0, pc)
