Move patch generation, specialization, regression, kernel selection and module signing helpers together, with their shared shell libraries. Update component Makefiles, CI, nightly jobs, packaging metadata, documentation and KUnit tooling references alongside the move. Adjust repository-root and source-inventory lookups for the deeper path. Resolve rhel-rpm-functions relative to kernel-functions through BASH_SOURCE, since it is also sourced by the QLogic extraction helpers. Keep the regression runner behavior and the nightly kernel matrix intact, including the existing checkpatch, sparse and smatch switches and policy.
