As no LMH (Limits Management Hardware) interrupts were seen, the firmware used for testing should not be able support them. This patch-set should still contain relevant modifications regarding LMH interrupts and CPU hotplug. Still, it would be good to test it on a platform which actually uses LMH interrupts.
