Subject[RFC GIT PULL rcu/next] RCU/hotplug fix
Hello, Ingo,

This pull request is for an RCU change that permits waiting for grace
periods started by CPUs late in the process of going offline. Lack of
this capability is causing failures:

Although these failures predate v4.12, and thus are in some sense not
regressions, it would be good for them to be fixed sooner rather than
later, hence this RFC pull request.
