- 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. Signed-off-by: Andi Kleen <ak@suse.de>
