From 62a8bd6c9246c0e1f19dfb8fc65ad7c4f7cac8bb Mon Sep 17 00:00:00 2001 From: Milton Miller Date: Wed, 22 Oct 2008 15:39:04 -0500 Subject: powerpc: Use is_kdump_kernel() linux/crash_dump.h defines is_kdump_kernel() to be used by code that needs to know if the previous kernel crashed instead of a (clean) boot or reboot. This updates the just added powerpc code to use it. This is needed for the next commit, which will remove __kdump_flag.
