This is a follow on from the series here

https://lore.kernel.org/linuxppc-dev/20230505071850.228734-1-npiggin@gmail.com/

With feedback addressed and Christophe's -mprofile-kernel for BE added,

https://lore.kernel.org/linuxppc-dev/20230506011814.8766-1-npiggin@gmail.com/

And dropped the last RFC patch that removes ELFv1 entirely. Maybe we can
wait one or two releases after this before doing that.

Thanks,
Nick
