Hi, I thought I'd just refresh the previous patchset, but in the meantime I found a way to avoid adding overhead to note_interrupt(), so I decided to change the approach. Patch [2/6] fixes the problem with IRQF_NO_SUSPEND and shared interrupts. The idea is to use wrapper handlers for all irqactions of the shared IRQs where at least one of them has IRQF_NO_SUSPEND set. Since the wrapper handler is now installed for all irqactions in the given irq_desc, it can track the return codes from the original handlers and "suspend" the IRQ if the interrupt is going to be unhandled eventually. All described in the changelog. This is independent of the handling of wakeup interrupts for suspend-to-idle. Patch [3/6] makes IRQs configured for system wakeup with enable_irq_wake() work for suspend to idle. It does that by using a (different) wrapper handler for all irqactions in the wakeup irq_descs and that wrapper handler takes care of all the ugly details. Again, all described in the changelog. Patches [1/6], [4-5/6] are unmodified and the last one addes documentation. Please review.
