The barrier was not intended to have anything to do with put_cpu()
either though since the barrier was added before put_cpu() arrived:

There's nothing in the commit comment explaining the barrier and I

Looks like it wasn't needed then either.
Agreed. I'll respin the patchset with the barrier removed.
