[PATCH] Fix zeroing on exception in copy_*_user
- Don't zero for __copy_from_user_inatomic following i386.
This will prevent spurious zeros for parallel file system writers when
one does a exception
- The string instruction version didn't zero the output on
exception. Oops.
Also I cleaned up the code a bit while I was at it and added a minor
optimization to the string instruction path.
