[PATCH] ppc32: Fix __copy_tofrom_user return value
Recently the __copy_tofrom_user routine was modified to avoid doing
prefetches past the end of the source array. However, in doing so we
introduced a bug in that it now returns the wrong value for the number
of bytes not copied when a fault is encountered. This fixes it to
return the correct number.
