* Name: up_idle
*
* Description:
* up_idle() is the logic that will be executed when their
* is no other ready-to-run task. This is processor idle
* time and will continue until some interrupt occurs to
* cause a context switch from the idle task.
*
* Processing in this state may be processor-specific. e.g.,
* this is where power management operations might be
* performed.
