__module_address undefined

[arm000]

Attempting to build kgdboe against 5.10.0-rc7 and I'm getting an undefined symbol error during modpost for "__module_address" Looking through git history it appears this patch in upstream Linux broke kgdboe:

commit 34e64705ad415ed7a816e60ef62b42fe6d1729d9

    modules: unexport __module_address

    __module_address is only used by built-in code.
