20  * PFNs are used to describe any physical page; this means
23  * This is the PFN of the first RAM page in the kernel
24  * direct-mapped view.  We assume this is the first page
54  * Conversion between a struct page and a physical address.
57  * struct page, the resulting pointer must be validated
58  * using VALID_PAGE().  It must return an invalid struct page
62  *  page_to_pfn(page)	convert a struct page * to a PFN number
63  *  pfn_to_page(pfn)	convert a _valid_ PFN number to struct page *
66  *  virt_to_page(k)	convert a _valid_ virtual address to struct page *
