#     powerpc/powernv: process all OPAL event interrupts with kopald
#     
#     Using irq_work for processing OPAL event interrupts is not necessary.
#     irq_work is typically used to schedule work from NMI context, a
#     softirq may be more appropriate. However OPAL events are not
#     particularly performance or latency critical, so they can all be
#     invoked by kopald.
#     
#     This patch removes the irq_work queueing, and instead wakes up
#     kopald when there is an event to be processed. kopald processes
#     interrupts individually, enabling irqs and calling cond_resched
#     between each one to minimise latencies.
#     
#     Event handlers themselves should still use threaded handlers,
#     workqueues, etc. as necessary to avoid high interrupts-off latencies
#     within any single interrupt.
