It's still way too early to backport these, but I'll maintain these
two branches for a little while:

https://git.kernel.org/pub/scm/linux/kernel/git/crng/random.git/log/?h=stable/linux-5.15.y
https://git.kernel.org/pub/scm/linux/kernel/git/crng/random.git/log/?h=stable/linux-5.17.y

So that when or if it does ever make sense to do that, it's been
maintained incrementally while the knowledge is fresh. I'm omitting
from those branches new feature development, such as vmgenid.
