The upcoming fine grained per task STIBP control needs to be updated on CPU
hotplug as well.
Split out the code which controls the strict mode so the prctl control code
can be added later. Mark the SMP function call argument __unused while at it.

The upcoming fine grained per task STIBP control needs to be updated on CPU
hotplug as well.
Split out the code which controls the strict mode so the prctl control code
can be added later. Mark the SMP function call argument __unused while at it.
