[PATCH] 2.5.13: remove VALID_PAGE
This patch removes VALID_PAGE(), as the test was always too late for
discontinous memory configuration. It is replaced with pfn_valid()/
virt_addr_valid(), which are used to test the original input value.
Other helper functions:
pte_pfn() - extract the page number from a pte
pfn_to_page()/page_to_pfn() - convert a page number to/from a page struct
