[PATCH] Fix the spurious unlock_cpu_hotplug false warnings
Cpu-hotplug locking has a minor race case caused because of setting the
variable "recursive" to NULL *after* releasing the cpu_bitmask_lock in the
function unlock_cpu_hotplug,instead of doing so before releasing the
cpu_bitmask_lock.
This was the cause of most of the recent false spurious lock_cpu_unlock
warnings.
This should fix the problem reported by Martin Lorenz reported in
http://lkml.org/lkml/2006/10/29/127.
Thanks to Srinivasa DS for pointing it out.
