Level triggered interrupts do not cause IRQS_PENDING to be set when they fire while "disabled" as the 'pending' state is always present in the level - they automatically refire where re-enabled. However the IRQS_PENDING flag is also used to abort a suspend cycle - if any 'is_wakeup_set' interrupt is PENDING, check_wakeup_irqs() will cause suspend to abort. Without IRQS_PENDING, suspend won't abort. Consequently, level-triggered interrupts that fire during the 'noirq' phase of suspend do not currently abort suspend. So set IRQS_PENDING even for level triggered interrupts, and make sure to clear the flag in check_irq_resend.
