You could use ClearPageReserved() + ioremap(), but ioremap() is limited to the first 4 GB.
The 4GB limit is okay for now. What does ClearPageReserved do? Does it make the kernel think that the page is part of high memory? -- Timur Tabi - ttabi@interactivesi.com Interactive Silicon - http://www.interactivesi.com When replying to a mailing-list message, please don't cc: me, because then I'll just get two copies of the same message. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
