Why do you need an output section for that? IOW: will this work too?
.data : ... { ...
VMLINUX_SYMBOL(__start___immediate) = .; \ *(__immediate) \ VMLINUX_SYMBOL(__stop___immediate) = .; \ ... }

Do you need to frame immediateindex by #ifdef CONFIG_IMMEDIATE / #endif? -- vda - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
