ncpfs: use vma_pages() to replace (vm_end - vm_start) >> PAGE_SHIFT
(*->vm_end - *->vm_start) >> PAGE_SHIFT operation is implemented as a inline funcion vma_pages() in linux/mm.h, so using it. Signed-off-by: Libin <huawei.libin@huawei.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
