* This is copied from the generic implementation and the C-struct

* for the OR32 arch optimizes too aggressively for the C-struct
* variant to work, so use the memmove variant instead.
*
* It may be worth considering implementing the unaligned access
* exception handler and allowing unaligned accesses (access_ok.h)...
* not sure if it would be much of a performance win without further
