- Move MAINTAINERS patch to be the last in the series.
- Allow custom number of top functions to be specified.
- Check for vallgrind and perf before executing the scripts.
- Ensure sufficient permissions when running the topN_perf script.
- Use subprocess instead of os.system
- Use os.unlink() for deleting intermediate files.
- Spread out the data extraction steps.
- Enable execution permission for the scripts.
