Revert "sparc64: Fix __copy_{to,from}_user_inatomic defines."
[ Upstream commit 16932237f2978a2265662f8de4af743b1f55a209 ]
This reverts commit 145e1c0023585e0e8f6df22316308ec61c5066b2.
This commit broke the behavior of __copy_from_user_inatomic when
it is only partially successful. Instead of returning the number
of bytes not copied, it now returns 1. This translates to the
wrong value being returned by iov_iter_copy_from_user_atomic.
xfstests generic/246 and LTP writev01 both fail on btrfs and nfs
because of this.
