The meaning of sym->kernel is obscure; it is set for in-kernel symbols loaded from Modules.symver. This happens only when we are building external modules, and it is used to determine whether to dump symbols to $(KBUILD_EXTMOD)/Modules.symver It is clearer to remember whether the symbol or module came from a dump file or ELF object. This changes the KBUILD_EXTRA_SYMBOLS behavior. Previously, symbols loaded from KBUILD_EXTRA_SYMBOLS are accumulated into the current $(KBUILD_EXTMOD)/Modules.symver Going forward, they will be only used to check symbol references, but not dumped into the current $(KBUILD_EXTMOD)/Modules.symver. I believe this makes more sense. sym->vmlinux will have no user. Remove it too.
