| * This is our kernel timer structure. |

| * - init |
| * Initialise the kernels jiffy timer source, claim interrupt |
| * using setup_irq. This is called early on during initialisation |
| * while interrupts are still disabled on the local CPU. |
| * - suspend |
| * Suspend the kernel jiffy timer source, if necessary. This |
| * is called with interrupts disabled, after all normal devices |
| * have been suspended. If no action is required, set this to |
| * NULL. |
| * - resume |
| * Resume the kernel jiffy timer source, if necessary. This |
| * is called with interrupts disabled before any normal devices |
| * are resumed. If no action is required, set this to NULL. |
| * - offset |
| * Return the timer offset in microseconds since the last timer |
| * interrupt. Note: this must take account of any unprocessed |
| * timer interrupt which may be pending. |
