/*

 * On lockdep we dont want to enable hardirqs in hardirq

 * context. Use local_irq_enable_in_hardirq() to annotate

 * kernel code that has to do this nevertheless (pretty much

 * the only valid case is for old/broken hardware that is

 * insanely slow).

 *

 * NOTE: in theory this might break fragile code that relies

 * on hardirq delivery - in practice we dont seem to have such

 * places left. So the only effect should be slightly increased

 * irqs-off latencies.
