IOW, say I have a physical address (e.g. 0x0CDB5000 on a 256MB machine), and I know (via the mem_map array) that it's not being used by anything. What I need to do know is allocate that page of memory so that no one else can allocate it (via a memory allocation function like get_free_page or malloc). Is this currently possible? If not, is anyone working on adding it to a future kernel? And if not, is anyone willing to help me implement it or at least tell me how I should proceed? -- Timur Tabi - ttabi@interactivesi.com Interactive Silicon - http://www.interactivesi.com -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
