[RFC PATCH 0/5] nohz: Move nohz kick out of scheduler IPI, v4

[Frederic Weisbecker <fweisbec@gmail.com>]

So this version now implements remote irq works using the generic IPI
interrupt available in most archs, as suggested by Peterz.

Keep in mind that the first patch is really just a draft to build the
mockup. It needs to be turned into an internal state set on boot or so.

Thanks,

Frederic Weisbecker (5):
      irq_work: Let arch tell us if it can raise irq work
      irq_work: Force non-lazy works to the IPI
      irq_work: Allow remote queueing
      nohz: Move full nohz kick to its own IPI
      nohz: Use IPI implicit full barrier against rq->nr_running r/w
