Date: Sun, 27 Jan 2008 15:38:39 -0800 From: Greg Kroah-Hartman <gregkh@...e.de> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...e.de>, Yinghai Lu <yhlu.kernel@...il.com>, Jacob Shin <jacob.shin@....com>, Ingo Molnar <mingo@...e.hu> Subject: [PATCH 2/5] x86: fix runtime error in arch/x86/kernel/cpu/mcheck/mce_amd_64.c This problem is due to the kobject rework recently done in this file. The mce_amd_64.c code uses some wierd forward calls to back out of the recursive way the code creates kobjects. Because of this, we need to verify that we have really created a kobject before calling kobject_uevent(). Many thanks to Yinghai Lu <yhlu.kernel@...il.com> for reporting the problem and testing.
