Subject: [PATCH tip/core/rcu 05/11] rcutorture: Test partial nohz_full= configuration

From: "Paul E. McKenney" <paulmck@...ux.vnet.ibm.com>

The current set of tests covers only cases where either all possible CPUs
are nohz_full= CPUs or none of them are.  Because there have been some
recent bug escapes in cases where only some of the CPUs are nohz_full=
CPUs, this commit add a configuration where only half of the CPUs are
nohz_full= CPUs.
