Patch Set 5:

I said it's better to have all operations in one file in the previous comment, but it might not work well. Because "struct exc_state" is defined at an ARM specific header file, so other architectures can't build it.
I will use __weak function and divide 2 files to implement probe_mb() for other architectures if I can't find any solutions.
