From a1a392f0b4f27604811bf8aa8d7636b3b4bc3803 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 4 Dec 2006 15:40:28 +0100 Subject: [PATCH] [S390] Bad kexec control page allocation. KEXEC_CONTROL_MEMORY_LIMIT is an unsigned long value and therefore should be defined as one. Otherwise the kexec control page can be allocated above 2GB which will cause a specification exception on the sam31 instruction in the s390 kexec relocation code.
