There might be a simple way to handler this; perhaps using
up_cpu_pause(), you could pause all of the other CPUs, perform
the restart/delete operation, then restart all other CPUs. But
this seems like a lot of work to support some garbage interfaces
that really should be removed anyway. These are unsafe, non-
standard interfaces that really have no place in an RTOS (unsafe
because you don't know what resources were held by the task when
it was restarted or deleted).
the restart/delete operation, then restart all other CPUs. A
better solution would be a new interface like up_cpu_stop().
This would be sent to all CPUs and if the task is running on
any of them, it would suspend the task and put it in the INVALID
state.

NOTE: Currently task_restart() is not even built if CONFIG_SMP=y.
The task_restart() test is also disabled in apps/examples/ostest
