This set of patches introduces the 128 byte alignment check, needed to avoid corruption if the dsp is meant to write to boundary portions of an unaligned chunk of memory. The second patch uses a field composed of 2 bits to distinguish if the mapped chunk is readable/writeable, so the check can be performed on w/rw chunks of memory.
