28  *	processed in time order they need to be sorted first.
31  *	time stamp lower than this record are processed (and displayed) before
49  * entries, the queue number and a time stamp. However the stack is sorted by
50  * the time stamps. The highest time stamp is at the bottom the lowest
51  * (nearest) time stamp is at the top. That sort order is maintained at all
58  * Each record is handled by s390_cpumsf_process_event(). The time stamp of
59  * the perf record is compared with the time stamp located on the auxtrace_heap
60  * top element. If that time stamp is lower than the time stamp from the
61  * record sample, the auxtrace queues will be processed. As auxtrace queues
64  * position in the auxtrace_buffer of that queue is remembered and the time
72  * Each sampling-data entry in the auxiliary trace data generates a perf sample.
73  * This sample is filled

79  * auxiliary traces entries until the time stamp of this record is reached
80  * auxtrace_heap top. This is triggered by ordered_event->deliver().
