Fixing the pages of a private memory object

Authorized programs can use IARV64 PAGEFIX to fix specified 4K pages in a single memory object. Page fixing prevents the system from stealing those pages. The ALETVALUE parameter tells the system where the memory object resides: the primary or the home address space. The LONG parameter tells the system the pagefix is expected to be of long duration (in seconds). On the RANGLIST parameter, the program provides a list of the page ranges that are to be fixed. The format of the list is:

IARV64 PAGEUNFIX requests that the system unpagefix the pages that back memory objects. A page remains fixed until the number of unpagefix operations for that page equals the number of pagefix operations. As with the pagefix request, the ALETVALUE parameter to specify that the memory object is in the primary or home address space and the program provides a list of page ranges.
