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.)
Thanks,
Ingo
