retpoline mitigation and 6.0

Thank you.
For reference, is there a way to turn *off* the retpoline which has
been enabled on the command line?
For init functions which run only at startup before any attacker can be
in the system, we currently mark the function
__attribute__((indirect_thunk("keep"))). Is there a clang equivalent?
It's not particularly important; a minor optimisation we can live
without if we have to.
