Those are simple enough, and usually not produced by root, instead by
whatever user is running java, rust, Node.js JIT code that end up
generating those /tmp/perf-PID.map for resolution of symbols in the
anonymous executable maps.
Having to use --force to resolve symbols in 'perf top' is a distraction,
as recently I experienced when node.js symbols were not being resolved
by 'perf top'.

That ends up generating this:
$ cat /tmp/build/perf/trace/beauty/generated/fadvise_advice_array.c
static const char *fadvise_advices[] = {
[0] = "NORMAL",
[1] = "RANDOM",
[2] = "SEQUENTIAL",
[3] = "WILLNEED",
[4] = "DONTNEED",
[5] = "NOREUSE",
};
