lock_device_hotplug() was recently introduced to serialize CPU & Memory
online/offline and hotplug operations, along with sysfs online interface
restructure (commit 4f3549d7).  With this new locking scheme,
cpu_hotplug_driver_lock() is redundant and is no longer necessary.

This patchset makes sure that lock_device_hotplug() covers all CPU online/
offline interfaces, and then removes cpu_hotplug_driver_lock().

v2:
  - Rebased to the pm tree, bleeding-edge.
  - Changed patch 2/4 to use lock_device_hotplug_sysfs().

The patch-set looks good to me.
