The __copy_user function can corrupt the stack in the case of a non-trivial length of data, and either of the first two move instructions cause an exception. This is because the fixup for these two instructions is mapped to the no_pop case, but these instructions execute after the stack is pushed. This change creates an explicit NO_POP exception mapping macro, and uses it for the two instructions executed in the trivial case where no stack pushes occur.
