- * @node_bootmem_map: is a bitmap pointer - the bits represent all physical
- *                   memory pages (including holes) on the node.
- * @last_end_off: the offset within the page of the end of the last allocation;
- *                if 0, the page used is full
- * @hint_idx: the PFN of the page used with the last allocation;
- *            together with using this with the @last_end_offset field,
- *            a test can be made to see if allocations can be merged
- *            with the page used for the last allocation rather than
- *            using up a full new page.
- * @list: list entry in the linked list ordered by the memory addresses
