This pull request contains the following branches:
 
 doc.2021.11.30c: Documentation updates, perhaps most notably Neil Brown's
 	writeup of the reference-counting analogy to RCU.
 
 exp.2021.12.07a: Expedited grace-period cleanups.
 
 fastnohz.2021.11.30c: Remove CONFIG_RCU_FAST_NO_HZ due to lack of valid
 	users. I have asked around, posted a blog entry, and sent this
 	series to LKML without result.
 
 fixes.2021.11.30c: Miscellaneous fixes.
 
 nocb.2021.12.09a: RCU callback offloading updates, perhaps most notably
 	Frederic Weisbecker's updates allowing CPUs booted in the
 	de-offloaded state to be offloaded at runtime.
 
 nolibc.2021.11.30c: nolibc fixes from Willy Tarreau and Anmar Faizi, but
 	also including Mark Brown's addition of gettid().
 
 tasks.2021.12.09a: RCU Tasks Trace fixes, including changes that increase
 	the scalability of call_rcu_tasks_trace() for the BPF folks
 	(Martin Lau and KP Singh).
 
 torture.2021.12.07a: Various fixes including those from Wander Lairson
 	Costa and Li Zhijian.
