sparc64: Delete now unused user copy fixup functions.

2016-11-21T09:11:38+00:00

[ Upstream commit 0fd0ff01d4c3c01e7fe69b762ee1a13236639acc ]

Now that all of the user copy routines are converted to return
accurate residual lengths when an exception occurs, we no longer need
the broken fixup routines.

sparc64: Prepare to move to more saner user copy exception handling.

2016-11-21T09:11:37+00:00

[ Upstream commit 83a17d2661674d8c198adc0e183418f72aabab79 ]

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.
