Bernhard Walle d85a60d85e Add IRQF_IRQPOLL flag (common code) ... irqpoll is broken on some architectures that don't use the IRQ 0 for the timer interrupt like IA64. This patch adds a IRQF_IRQPOLL flag. Each architecture is handled in a separate pach. As I left the irq == 0 as condition, this should not break existing architectures that use timer_irq == 0 and that I did't address with that patch (because I don't know). This patch: This patch adds a IRQF_IRQPOLL flag that the interrupt registration code could use for the interrupt it wants to use for IRQ polling. Because this must not be the timer interrupt, an additional flag was added instead of re-using the IRQF_TIMER constant. Until all architectures will have an IRQF_IRQPOLL interrupt, irq == 0 will stay as alternative as it should not break anything. Also, note_interrupt() is called on CPU-specific interrupts to be used as interrupt source for IRQ polling.
