[PATCH 0/5] metag: smp/hotplug fixes

[James Hogan]

Kirill Tkhai kindly pointed out a bug in the metag SMP code, prompting
me to give it a bashing and weed out the hotplug bugs that have crept in
(or been around for a while). This patchset fixes various issues noticed
that I intend to apply for v3.11.

They're all short patches so please do give them a glance over in case
I've misunderstood anything.

James Hogan (5):
  metag: use clear_tasks_mm_cpumask()
  metag: smp: enable irqs after set_cpu_online
  metag: smp: don't spin waiting for CPU to start
  metag: kick: prevent nested kick handlers
  metag: cpu hotplug: route_irq: preserve irq mask
