4.17-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Biggers <ebigg...@google.com>
commit 0567fc9e90b9b1c8dbce8a5468758e6206744d4a upstream.
The ALIGN() macro needs to be passed the alignment, not the alignmask
(which is the alignment minus 1).
Fixes: b286d8b1a690 ("crypto: skcipher - Add skcipher walk interface")
