No longer falls back to the real system call. Can you tell me the kernel version where this change was made? It would be useful to include that in the text, I think. In fact, if you knew the kernel commit that made the change, that would also be of interest. Also, your patch changes just the entry for ppc/64. Does the same statement hold true for ppc/32?
