* The group object is the most important object in the device driver,

* The reason for this is that operations on the MMU will affect all
* cores connected to this MMU (a group is defined by the MMU and the
* cores which are connected to this).
* The group lock is thus the most important lock, followed by the
* GP and PP scheduler locks. They must be taken in the following
