Merge remote-tracking branch 'qatar/master'
* qatar/master: ARM: ac3dsp: optimised update_bap_counts() mpegaudiodec: Fix av_dlog() invocation. h264/10bit: add HAVE_ALIGNED_STACK checks. Update 8-bit H.264 IDCT function names to reflect bit-depth. Add IDCT functions for 10-bit H.264. mpegaudioenc: Fix broken av_dlog statement. Employ correct printf format specifiers, mostly in debug output. ARM: fix MUL64 inline asm for pre-armv6 Conflicts: libavcodec/mpegaudioenc.c libavformat/ape.c libavformat/mxfdec.c libavformat/r3d.c Merged-by: Michael Niedermayer <michaelni@gmx.at>
