The parisc architecture recently reimplemented the memcpy function and their reimplementation crashed when source and destination overlapped. The crash happened in the function ide_complete_cmd where memcpy is called with the same source and destination pointer. According to the C specification, memcpy behavior is undefined if the source and destination range overlaps. This patches fixes the undefined behavior.
