[PATCH] x86-64: Allow to run a program when a machine check event is detected
When a machine check event is detected (including a AMD RevF threshold overflow event) allow to run a "trigger" program. This allows user space to react to such events sooner. The trigger is configured using a new trigger entry in the machinecheck sysfs interface. It is currently shared between all CPUs. I also fixed the AMD threshold handler to run the machine check polling code immediately to actually log any events that might have caused the threshold interrupt. Also added some documentation for the mce sysfs interface. Signed-off-by: Andi Kleen <ak@suse.de>
