/* Report a change in status down the driver chain.
* We want to report the mouse as enabled if and only if the guest

* can receive mouse events when the bus mouse is disabled.
* Enabling interrupts constitutes enabling the bus mouse. The mouse
* is considered disabled if interrupts are disabled for several
* consecutive mouse timer ticks; this is because the interrupt handler
* in the guest typically temporarily disables interrupts and we do not
* want to toggle the enabled/disabled state more often than necessary.
