-/* Provide an idle-task body which switches the
- * CPU into power-save mode when idle. Any exception
- * (including an interrupt/external-exception)
- * wakes it up.
- *
- * IIRC - this cannot be used on real hardware due
- * to errata on many chips which is a real
- * pity. However, when used under qemu it
- * saves host-CPU cycles.
- * While qemu-0.12.4 needed to be patched
- * (would otherwise hang because an exception
- * didn't clear MSR_POW) qemu-0.14.1 seems
- * to work fine.
