perf symbols: Correct comment wrt kallsyms loading In kallsyms_parse() when calling process_symbol() (a callback argument to kallsyms_parse()), we pass start as both start & end (ie: start=start, end=start). In map__process_kallsym_symbol(), the length is calculated as 'end - start + 1', making the length 1, not 0. Essentially, start & end define an inclusive range.
