From baf2aeb3d9e286add823bcaea5442ad4ee34f6e4 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 4 Dec 2006 15:40:36 +0100 Subject: [PATCH] [S390] Misaligned wait PSW at memory detection. If the memory detection code would ever reach the point where it would load the wait psw, it would generate a specification exception and the system would crash at ipl time. This is because of a misaligned wait psw. It needs to be on a double word boundary instead of a word boundary.
