12 * Because of broken hardware we have to enable interrupts or the CPU
13 * will never wakeup... Acctualy it is not very good to enable
14 * interrupts first since scheduler can miss a tick, but there is
15 * no other way around this. Platforms that needs it for power saving
16 * should enable it in init code, since by default it is
17 * disabled.
