Argh, those are called get_UNaligned_*, not get_aligned_*. > There are more lines in raid6.c which need the same fix, basically everything > with * (unative_t *). Oh, and you will somehow need to guard this with #if BITS_PER_LONG == 64 ... #else ... #endif respectively since you need to use different versions (64 vs. 32) of get_unaligned_* depending on the size of unative_t.
