Kernel scripts/ set to shed its last Perl utilities

Breno Rodrigues Alves has posted an RFC to convert the final seven Perl utilities in the Linux kernel's scripts/ directory to Python 3, completing a sweep that would leave no Perl in that tree.

Twelve tools were already ported in an earlier series. This follow-up covers the rest as faithful one-to-one reimplementations: same command-line interfaces, same output, same behavior, and no dependencies beyond the Python standard library. Five were verified byte-for-byte against their Perl counterparts on synthetic or real inputs; the other two, which need build artifacts such as vmlinux or a .config, track the original logic directly.

The utilities span routine developer and packaging work: measuring function stack depth from objdump, extracting module signatures and embedded system certificates, walking header include graphs for cycles, flagging unknown Kconfig symbol references, sorting MAINTAINERS sections, and shrinking a kernel config to the modules loaded on the running system.

If accepted, the change drops Perl from a central set of in-tree scripts that kernel builders and maintainers still touch, aligning that tooling with Python already common in modern Linux development environments.
