Side-note: in `get_function_bounds()`, I see `kallsyms_lookup()` being
used, but the name seems discarded? Can
`kallsyms_lookup_size_offset()` be used instead, thus avoiding the
usage of the buffer there to begin with?

Side-note 2: in `scanhex()`, I see a loop `i<63` using `tmpstr` which
then is used to do a `kallsyms_lookup_name()`, so I guess symbols
larger than 64 couldn't be found. I have no idea about what are the
external constraints here, but perhaps it is possible to increase the
`line` buffer etc. to then allow for bigger symbols to be found.

Cheers,
Miguel
