From: Leon Romanovsky <leonro@xxxxxxxxxxxx>
Memory object gives to the user ability to manipulate over general
properties of memory for the specific devices. The memory properties
have broader usage than dev object can provide.
For example, on-demand-paging (ODP) configurations are mostly software related.
