next: drm/atomic: Use copy_from_user to copy 64 bit data from user space
Copying 64 bit data from user space using get_user is not supported
on all architectures, and may result in the following build error.
ERROR: "__get_user_bad" [drivers/gpu/drm/drm.ko] undefined!
Avoid the problem by using copy_from_user.
