Hi,
This version fixes the following concerns from Peterz:
* Warn _before_ work claim on irq_work_queue_on()
* Warn on in_nmi() while remote queueing
* Only disabled preemption (and not irqs) on local queueing
Thanks.

Thanks,

irq_work: Split raised and lazy lists
irq_work: Shorten a bit irq_work_needs_cpu()
irq_work: Implement remote queueing
nohz: Move full nohz kick to its own IPI
nohz: Use IPI implicit full barrier against rq->nr_running r/w
