* Conversion between a struct page and a physical address.

- * 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.
- *
* page_to_pfn(page) convert a struct page * to a PFN number
* pfn_to_page(pfn) convert a _valid_ PFN number to struct page *
