Merge tag 'lkmm.2024.05.10a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu

Pull LKMM documentation updates from Paul McKenney:
"This upgrades LKMM documentation, perhaps most notably adding a number
of litmus tests illustrating cmpxchg() ordering properties.

TL;DR: Failing cmpxchg() operations provide no ordering"

Documentation/litmus-tests: Make cmpxchg() tests safe for klitmus

The four litmus tests in Documentation/litmus-tests/atomic do not

This commit therefore adjusts these tests to declare all local variables.
