I think the only complexity it might introduce is with the need to
handle a rescheduling of all tasks assigned to the now disable
CPU/core. But, frankly, I wouldn't handle anything much differently -
set a flag that the core is unavailable and stop scheduling new tasks,
when the CPU is idled, put it to sleep... the longer it doesn't have any
tasks the deeper into the sleep states it should go with the normal
scheduler code.
But, I've only glanced at the code changes applied... there may be more
at play.
