Not a huge fan. That "r" makes sense to you ("raw" atomic), but it
makes no sense to a user. An atomic isn't "raw" to anybody else. It's
just an atomic.

Also, we have 'atomic64_t", which this doesn't cover at all.

I'd suggest just %pA, %pA64, %pAkref or something. Which leaves us the
choice to add more atomic versions later without having to make up
random one-letter things that make no sense.
