This patch modifies ia64's show_mem() to walk the vmem_map page tables and rapidly skip forward across regions where the page tables are missing. This prevents the pfn_valid() check from causing numerous unnecessary page faults. Without this patch on a 512 node 512 cpu system where every node has four memory holes, the show_mem() call takes 1 hour 18 minutes. With this patch, it takes less than 3 seconds.
