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 <[EMAIL PROTECTED]> for reporting the
problem and testing.
