Subject: [GIT PULL] nohz: Full dynticks timekeeping and RCU improvement

Hi Ingo,

So with this we are mostly done with the RCU and timekeeping sides.
The interface is still a bit spartan:

* Need to keep the boot CPU outside full dynticks range.
* Need to have nohz_full= be a subset of rcu_nocbs=

Note that none of this is thought to be fixed on the rock. It's
just a KISS interface settlement so that we can focus on the
central things.

These constraints will likely be removed in the future.

Please pull from:

HEAD: da922312f6980cb9214a64f7303f6cb3cf93626f

Thanks.

  nohz: Force boot CPU outside full dynticks range
  nohz: Ensure full dynticks CPUs are RCU nocbs
  nohz: New option to default all CPUs in full dynticks range
