Yes.  Another fix would be to have the idle thread call poll_idle() like
it did in 4.x.  The comment for P_NOLOAD says
	/* Ignore during load avg calculations. */
Looking at the threads that set P_NOLOAD, all of them are appear to
do minimal work.  Both idle_poll() and vm_page_zero_idle() used
to be called by the idle process.  Mapping them back to the idle
process seems reasonable to me.
