This merge is necessary as Lai's CPU hotplug restructuring series
depends on the CPU hotplug bug fixes in for-3.6-fixes.

The merge creates one trivial conflict between the following two
commits.

 96e65306 "workqueue: UNBOUND -> REBIND morphing in rebind_workers() should be atomic"
 e2b6a6d5

 "workqueue: use system_highpri_wq for highpri workers in rebind_workers()"

Both add local variable definitions to the same block and can be
merged in any order.
