 * Standard way to access the cycle counter.

 * Currently only used on SMP for scheduling.

 * Only the low 32 bits are available as a continuously counting entity.

 * But this only means we'll force a reschedule every 8 seconds or so,

 * which isn't an evil thing.

 *

 * We know that all SMP capable CPUs have cycle counters.
