Pull scftorture updates from Paul McKenney:

 - Avoid divide operation

 - Fix cleanup code waiting for IPI handlers

 - Move memory allocations out of preempt-disable region of code for
   PREEMPT_RT compatibility

 - Use a lockless list to avoid freeing memory while interrupts are
   disabled, again for PREEMPT_RT compatibility

 - Make lockless list scf_add_to_free_list() correctly handle freeing a
   NULL pointer
