This doesn't actually accomplish anything useful, though, so stop doing it. (vmac_update() does have an alignment bug, where it assumes u64 alignment when it shouldn't, but that bug exists both before and after this patch.) This is a prerequisite for removing support for nonzero alignmasks from shash.
