From: Geert Uytterhoeven <[email protected]> At .smp_prepare_cpus() time, CPUs 1-3 are still powered down: - The bootloader doesn't enable CPUs 1-3, - Non-boot CPUs are disabled by kexec before starting the new kernel.
Hence there is no need to try to power them down again, as it will fail silently with -EIO anyway.
