These look good to me, except that in cracker.c there's this redundant
piece left:
#if CRK_PREFETCH && defined(__SSE2__)
#include <emmintrin.h>
#endif
it becomes redundant with the addition of:
#if CRK_PREFETCH && defined(__SSE__)
#include <xmmintrin.h>
#endif
higher in the same file. Please remove the __SSE2__ / emmintrin.h piece.

I think not. Let's keep things as they are.
Thanks!
