Switch the DO_ONCE() macro from the deprecated jump label API to the new one. The new one is more readable, and for DO_ONCE() it also makes the generated code more icache-friendly: now the one-time initialization code is placed out-of-line at the jump target, rather than at the inline fallthrough case.
