How about trying what I suggested, to make reboot affine to the boot CPU explicitly, not by shutting down all the other CPUs, but by set_cpus_allowed() or so? That should solve the regression, without the ugly special-casing - while giving time to address the hot-unplug performance bottleneck. Once that is done disable_nonboot_cpus() can be used again for reboot. (But no strong feelings either way - both solutions are a workaround in a sense.)
