These errors occur in Linus's tree so could this go before that one then
it could just update the instances of KCFI_ADDRESSABLE? I don't have a
strong opinion, I found these series of errors tangentially but this
feels like something that could go via x86/urgent and that series could
just rebase on it.

Cheers,
Nathan
