Subject: [patch 01/38] memory detection: stop at first memory hole.
Date: Fri, 27 Apr 2007 16:05:04 +0200 [thread overview]
Message-ID: <20070427140511.915140111@de.ibm.com> (raw)
In-Reply-To: <20070427140503.087958775@de.ibm.com>
[-- Attachment #1: 001-memory-hole.diff --]
[-- Type: text/plain, Size: 1137 bytes --]
From: Heiko Carstens <heiko.carstens@de.ibm.com>
If both sclp and diag memory detection don't work stop at the first
memory hole. Otherwise the code might loop forever...
