Add an abstraction layer to the 64-bit AIM MMU's page table manipulation
logic to support modifying the page table through a hypervisor. This
uses KOBJ inheritance to provide subclasses of the base 64-bit AIM MMU
class with additional methods for page table manipulation.
Many thanks to Peter Grehan for suggesting this design and implementing
the MMU KOBJ inheritance mechanism.
