From 29c380f5f06d0c5a320b9bb6f8987065e7b81c91 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Fri, 27 Apr 2007 16:01:04 +0200 Subject: [PATCH] [S390] memory detection: stop at first memory hole. If both sclp and diag memory detection don't work stop at the first memory hole. Otherwise the code might loop forever...
