/*
* 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.
