Linus Torvalds 2656821f1f RCU pull request for v6.7
This pull request contains the following branches:
 
 rcu/torture: RCU torture, locktorture and generic torture infrastructure
 	updates that include various fixes, cleanups and consolidations.
 	Among the user visible things, ftrace dumps can now be found into
 	their own file, and module parameters get better documented and
 	reported on dumps.
 
 rcu/fixes: Generic and misc fixes all over the place. Some highlights:
 
 	* Hotplug handling has seen some light cleanups and comments.
 
 	* An RCU barrier can now be triggered through sysfs to serialize
 	memory stress testing and avoid OOM.
 
 	* Object information is now dumped in case of invalid callback
 	invocation.
 
 	* Also various SRCU issues, too hard to trigger to deserve urgent
 	pull requests, have been fixed.
 
 rcu/docs: RCU documentation updates
 
 rcu/refscale: RCU reference scalability test minor fixes and doc
 	improvements.
 
 rcu/tasks: RCU tasks minor fixes
 
 rcu/stall: Stall detection updates. Introduce RCU CPU Stall notifiers
 	that allows a subsystem to provide informations to help debugging.
 	Also cure some false positive stalls.
