No changes are being made to the individual files added here; they're 1:1 copies of the ones in redhat-rpm-config. Note the kernel-rpm-macros version - the latest c9s build is versioned after its parent SRPM which is redhat-rpm-config-184-1, so we need to make this one NVR-newer to allow for clean upgrades. The respective removals from redhat-rpm-config are tracked in #1959924. Resolves: #1959914
