- * Requirement:

- *
- * Theory:
- * We "misuse" the Linux memory management system. We use alloc_page
- * to allocate a page and then mark it as reserved. The Linux memory
- * management system will then ignore the "offset", "next_hash" and
- * "pprev_hash" entries in the mem_map for this page.
- *
- * We then use a bitstring in the "offset" field to mark which segments
- * of the page are in use, and manipulate this as required during the
- * allocation and freeing of these small pages.
- *
- * We also maintain a queue of pages being used for this purpose using
- * the "next_hash" and "pprev_hash" entries of mem_map;
