From d1bf85902c28dd990c08f1703ea94109223549a7 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Fri, 26 Feb 2010 22:37:30 +0100 Subject: [S390] cio: fix storage key handling Some parts of cio do not shift PAGE_DEFAULT_KEY correctly and end up with an incorrect key in their data structures. Since the default key is zero this doesn't really matter. However if somebody would use key-controlled protection for debugging purposes it would be quite helpful if all of this would work as expected. Also remove a stale declaration.
