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.
