So the __UNIQUE_ID() plan doesn't work, as a consequence of the logic
inside ignore_param() to shuffle the string name into initdata.

As everything is in .initdata, it doesn't actually interact with LIVEPATCH.

I've committed this patch with an extra note to try and prevent
TEMP_NAME() being used in wider contexts.
