sparc64: Prepare to move to more saner user copy exception handling.
The fixup helper function mechanism for handling user copy fault handling is not %100 accurrate, and can never be made so. We are going to transition the code to return the running return return length, which is always kept track in one or more registers of each of these routines. In order to convert them one by one, we have to allow the existing behavior to continue functioning. Therefore make all the copy code that wants the fixup helper to be used return negative one. After all of the user copy routines have been converted, this logic and the fixup helpers themselves can be removed completely. Signed-off-by: David S. Miller <davem@davemloft.net>
