Certain uses of "do once" functionality reside outside of fast path,

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() ?? Anyway, besides my bike-shedding comment above... Acked-by: Steven Rostedt (VMware) <rostedt@goodmis.org> -- Steve
