From c1e26e1ef7ab50f30e5fbf004fe96ed44321ca78 Mon Sep 17 00:00:00 2001 From: Jan Glauber Date: Fri, 6 Jan 2006 00:19:17 -0800 Subject: [PATCH] s390: in-kernel crypto rename Replace all references to z990 by s390 in the in-kernel crypto files in arch/s390/crypto. The code is not specific to a particular machine (z990) but to the s390 platform. Big diff, does nothing..
