From d9a9855d0b06ca6d6cc92596fedcc03f8512e062 Mon Sep 17 00:00:00 2001 From: Simon Horman Date: Sat, 18 Oct 2008 20:28:29 -0700 Subject: [PATCH] always reserve elfcore header memory in crash kernel elfcore header memory needs to be reserved in a crash kernel. This means that the relevant code should be protected by CONFIG_CRASH_DUMP rather than CONFIG_PROC_VMCORE.
