swapper is no process for page swap but it's a kernel system process to manage
the idle task.  It's called so only from historical reason.

And native_safe_halt() just calls the HLT instruction, i.e. CPU is in idle. 
That said, there is really no CPU load on your system.

So, this doesn't clarify why the load shows 1.  At least, perf didn't see any
actually consuming tasks there.
