IA64 has a special virtual address range for huge page tables. We would first have to introduce various page sizes in the virtual address range for huge pages (I think Ken is working on something like that) and then the fallback could only be to a "huge" page of order 0. But then the page would still not behave like a normal page. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
