  * Conversion between a struct page and a physical address.

- * Note: when converting an unknown physical address to a
- * struct page, the resulting pointer must be validated
- * using VALID_PAGE().  It must return an invalid struct page
- * for any physical address not corresponding to a system
- * RAM address.
