I doubt you can get that much except at early boot. But, if the pages don't actually need to be physically contiguous, then you can use vmalloc() - it'll give you a virtually contiguous range but the pages are not nessesarily physically contiguous. Why do you need this much btw? -- Jesper Juhl <jesper.juhl@...il.com> Don't top-post http://www.catb.org/~esr/jargon/html/T/top-post.html Plain text mails only, please http://www.expita.com/nomime.html - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
