Basically what you are saying, is to have his code do what the NMI code originally did, but can't now, due to there being another IDT table (from Seiji's changes). static void switch_to_trace_idt(void *arg) { load_idt(&trace_idt_descr); } static void restore_original_idt(void *arg) { load_idt(this_cpu_ptr(&idt_descr)); } -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
