Ugh, I had forgotten to sign the tag. Should be fixed now, sorry about that.

>
>- Fix an age old bug involving jump_calls and static_labels when
> CONFIG_MODULE_UNLOAD=n. When CONFIG_MODULE_UNLOAD=n, it means you
> can't unload modules, so normally the __exit sections of a module are
> not loaded at all. However, dynamic code patching (jump_label,
> static_call, alternatives) can have sites in __exit sections even if
> __exit is never executed.

> Reported by Peter Zijlstra: "Alternatives, jump_labels and static_call
> all can have relocations into __exit code. Not loading it at all would
> be BAD." Therefore, load the __exit sections even when
> CONFIG_MODULE_UNLOAD=n, and discard them after init.
