 492           calls to bootstage_mark() with a suitable BOOTSTAGE_ID from
 493           bootstage.h. Only a single entry is recorded for each ID. You can
 494           give the entry a name with bootstage_mark_name(). You can also
 495           record elapsed time in a particular stage using bootstage_start()
 496           before starting and bootstage_accum() when finished. Bootstage will
 497           add up all the accumated time and report it.
 498
 499           Normally, IDs are defined in bootstage.h but a small number of
 500           additional 'user' IDs can be used but passing BOOTSTAGE_ID_ALLOC
 501           as the ID.

 571           This happens through a call to bootstage_stash(), typically in
 572           the CPU's cleanup_before_linux() function. You can use the
