From: Steven Rostedt <srost...@redhat.com>
The commit "cpu/rt: Rework cpu down for PREEMPT_RT" changed the double
meaning of the cpu_hotplug.lock, where it was a spinlock for RT and a
mutex for non-RT, to just a mutex for both. But the initialization of
the variable was not updated to reflect this change.
