Not possible anymore. The kernel's IRQ handling has changed such that generic code now ensures that IRQs are disabled irrespective of the IRQF_DISABLED flag. All IRQ handlers are called with IRQs disabled, and they remain that way until they call local_irq_enable(). _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
