Which architectures are still missing? I think we finally need to
get everyone in line instead of repeatedly working around the lack
of minor arch support.

Hi Arnd,
If you don't mind, can I integrate this into the original patch in the queue?
Thanks,

Not all architectures support get_user() with a 64-bit argument:

Yes, I think that would be good anyway, it may take a little longer to fix all
