How much time is really wasted where one cpu is doing nothing but
waiting on one kthread to complete nowadays?

   Most of our kernel is still under the BGL, and its going to stay that
   way at least until after the 1:1 threading work is finished, and
   probably a good chunk of the syslink work too.

   There has been progress around the edges.  e.g. the file descriptor
   and file pointer subsystems are MP safe now, NETIF devices are
   protected by their own serializer, the route table is per-cpu, and
   a few other things.
