hi,
i dont understand, the guard page will be automatically added in
__get_vm_area_node, http://lxr.free-electrons.com/source/mm/vmalloc.c 
line 201

 size += PAGE_SIZE;


> +	 * it's worked so far.  The +1 is because __get_vm_area
> allocates a +	 * guard page, so we need space for that. */
>  	switcher_vma = __get_vm_area(TOTAL_SWITCHER_PAGES * PAGE_SIZE,
> -				       VM_ALLOC, SWITCHER_ADDR, VMALLOC_END);
> +				     VM_ALLOC, SWITCHER_ADDR, SWITCHER_ADDR
> +				     + (TOTAL_SWITCHER_PAGES+1) * PAGE_SIZE);
