This one looks fine on its own merits, so I grabbed it from your git tree:

ecdadb5289d1 ("headers/uninline: Uninline multi-use function: finish_rcuwait()")

>       headers/deps: RCU: Remove __read_mostly annotations from externs

And same with this one:

1c8af2245fd7 ("headers/deps: RCU: Remove __read_mostly annotations from externs")


Of course, if you would rather keep these, please let me know and I will
drop them.
