That is fine when the export belongs to vmlinux, and not fine when it belongs to a module: the livepatch would gain a module dependency nobody declared, and late module patching lets the patch load first.

A patch may introduce a reference the original object did not have.  That
is fine when the export belongs to vmlinux, and not fine when it belongs to
a module: the livepatch would gain a module dependency nobody declared, and
late module patching lets the patch load first.

This tests the behavior of commit 72d76d0c18eb ("objtool/klp: Allow new
references to module exports").
