For the record, this breaks allmodconfig with clang (I haven't seen a
formal report on it anywhere and this missed -next coverage because
Stephen is on vacation):

I know you don't take patches during the merge window, so I guess we'll
just have to have x86_64 allmodconfig be broken with clang for -rc1? :/
