Subject: [PATCH 0/6] rcu/nocb: Last prep work before cpuset interface v2

Changes since v1 after Paul's reviews:

* Clarify why the DEL vs ADD possible race on rdp group list is ok [1/6]
* Update kernel parameters documentation [5/6]
* Only create rcuo[sp] kthreads for CPUs that have ever come online [4/6]
* Consider nohz_full= on changelogs

HEAD: da51363e5ddf54d6ce9c2cfbab946f8914519290

Thanks,
