unixbhaskar shares a report from Phoronix: The X86_NATIVE_CPU Kconfig build time option has been merged for the Linux 6.16 merge window as an easy means of enforcing "-march=native" compiler behavior on AMD and Intel processors to optimize your kernel build for the local CPU architecture/family of your system. In addition to setting the "-march=native" compiler option for the Linux kernel C code, enabling this new Kconfig build option also sets "-Ctarget-cpu=native" for the kernel's Rust code too. "If the detailed benchmark shows some improvement with the option selected, then distros might start to adopt it for their flavor."
