Commit ccbc60d3e19a1b6ae66ca0d89b3da02dde62088b ('topology: Provide
CPU topology in sysfs in !SMP configurations') causes a crash at boot

there is a CPU device for each online CPU whereas some architectures
that do not support SMP or cpufreq do not register any CPU devices.
Check for this before trying to use a device.

Works on its own or combined with "[PATCH 2/2] cpu: Register a generic
CPU device on architectures that currently do not".

when I'm talking to journalists I just say "programmer" or something like that.
