From 406f104b4172de7452702c6810807c1b0132ba22 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Fri, 10 Jul 2009 13:18:26 +0800 Subject: crypto: sha1-s390 - Add export/import support This patch adds export/import support to sha1-s390. The exported type is defined by struct sha1_state, which is basically the entire descriptor state of sha1_generic.
