Subject: [PATCH 0/2] multi-threading device shutdown

Do a faster shutdown by calling dev->*->shutdown(dev) in parallel.
device_shutdown() calls these functions for every single device but
only using one thread.

Since, nothing else is running on the machine by the device_shutdown()
s called, there is no reason not to utilize all the available CPU
resources.

  ixgbe: release lock for the duration of ixgbe_suspend_close()
  drivers core: multi-threading device shutdown
