Certain uses of "do once" functionality reside outside of fast path, and so do not require jump label patching via static keys, making existing DO_ONCE undesirable in such cases. Replace uses of __section(".data.once") with DO_ONCE_LITE(_IF)?I hate the name "_LITE" but can't come up with something better. Maybe: DO_ONCE_SLOW() ??
Or rename the original DO_ONCE() to DO_ONCE_FAST() because it is more tricky to be fast. And call the "normal" implementation DO_ONCE().
Anyway, besides my bike-shedding comment above...
