/*

 * 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.
