Gah!  Please accept my apologies for the hassle!

In the short term, I have reset rcu/next to the commit preceding
42e3e3c6a774 ("EXP preempt/dynamic: Introduce preempt mode accessors").
This could cause some trouble for a few corner-case -next users, but...

Longer term, this is excellent news, because it means that I can drop
that commit from my tree entirely and rebase my stack on top of the
version of that same commit that is just now in -tip.

Understood, and thank you.

The next time that I am forced to choose between propagating a bug into
-next on the one hand and precisely following the above rules on the
other, I will consult with you beforehand.  Please accept my apologies
for failing to have done so this time.

							Thanx, Paul
