From 66f6ce5e52f2f209d5bf1f06167cec888f4f4c13 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Wed, 15 Jul 2009 12:40:40 +0800 Subject: crypto: ahash - Add unaligned handling and default operations This patch exports the finup operation where available and adds a default finup operation for ahash. The operations final, finup and digest also will now deal with unaligned result pointers by copying it. Finally export/import operations are will now be exported too.
