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...

Same here :-)
