Subject: [PATCH 0/6] nohz: Move nohz kick out of scheduler IPI, v8
Date: Tue, 10 Jun 2014 17:15:03 +0200	[thread overview]
Message-ID: <1402413309-3415-1-git-send-email-fweisbec@gmail.com> (raw)

So this set happens to have more changes than expected because I
found out that the timer list full nohz kick also relies on the scheduler
IPI. So I had to convert it as well, hence a few more change splitups.

Changes:

* Check also raised lists from irq_work_needs_cpu() (thanks Peterz)

* Comment on SMP functions priority in
  generic_smp_call_function_single_interrupt() because IPI callbacks there
  are often synchronous as opposed to irq works. (thanks Peterz)

* s/native_send_call_func_single_ipi/native_send_call_func_single_ipi
  (thanks Eric Dumazet)

* Only build irq_work_queue_on() on CONFIG_SMP, fixes some broken builds

* Convert full nohz timer list kick

Thanks,
