Thomas Gleixner 5c87f0c04a clockevents: Prevent clockevent_devices list corruption on cpu hotplug ...

commit bb6eddf7676e1c1f3e637aa93c5224488d99036f upstream.

Xiaotian Feng triggered a list corruption in the clock events list on
CPU hotplug and debugged the root cause.

If a CPU registers more than one per cpu clock event device, then only
the active clock event device is removed on CPU_DEAD. The unused
devices are kept in the clock events device list.

On CPU up the clock event devices are registered again, which means
that we list_add an already enqueued list_head. That results in list
corruption.

Resolve this by removing all devices which are associated to the dead
CPU on CPU_DEAD.
