Setting-up-page-tables

Setting up the page tables for a user-level program's run

Recall that when the value of the field app-view is nil, the x86 model offers the system-level view of x86 machines. It's only in this view that memory read and write functions like rml08 and wml08 will do a page-table walk. See section app-view for details.
