64-bit get_user is currently unsupported on ARM, although it appears work is
ongoing [1].

Thanks for info, Christopher! What arm camp is using then, copy-from-user?

copy_from_user should work on all architectures. I believe a 64-bit get_user
is currently unsupported on most 32-bit architectures, x86-32 being a notable
exception.

Thanks, I'll update.
