Merge branch 'for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/rcu
Pull RCU fix from Paul E. McKenney:
"This additional v4.18 pull request contains a single commit that fell
through the cracks:
Provide early rcu_cpu_starting() callback for the benefit of the
x86/mtrr code, which needs RCU to be available on incoming CPUs
earlier than has been the case in the past."
