From 7af0d6f753f5adf773f99470666b50490d3379f1 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Tue, 4 Dec 2007 16:09:05 +0100 Subject: [PATCH] [S390] Make sure the restore psw masks are initialized. In case of TRACE_IRQFLAGS the restore psw masks will not be initialized if noexec is turned on. This will lead to an immediate system crash.
