[PATCH v1 0/2] genirq: support multiple IRQ notifier.

[Weongyo Jeong <weongyo.linux-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

Each irq_desc only supports one IRQ affinity notifier at current
implementation so when we try to register another notifier, it silently
unregister previous entry and register new one.

However the problem is that if CONFIG_RFS_ACCEL is set, at current
implementation no way to set additional IRQ affinity notifier for
some NIC cards RFS enabled because it already used for RFS.
With this patch we can register multiple IRQ affinity notifiers.

Weongyo Jeong (2):
  genirq: clean up for irq_set_affinity_notifier().
  genirq: support multiple IRQ notifier.
