* commit '0c15a9aa7e1654a19144eb594f9639a57fd47482': sh4: Remove dubious aligned dsputil code Conflicts: libavcodec/sh4/dsputil_align.c libavcodec/sh4/h264chroma_init.c libavcodec/sh4/hpeldsp.c libavcodec/sh4/qpel.c If someone wants to maintain the sh4 code in ffmpeg, wants to add more optimizations, or volunteers to maintain any of what is removed here and can confirm that they are faster. Then please contact us! Merged-by: Michael Niedermayer <michaelni@gmx.at>
