Merge remote-tracking branch 'qatar/master' 

* qatar/master:
  arm: intreadwrite: disable inline asm for gcc 4.7 and later
  arm: intreadwrite: fix inline asm constraints for gcc 4.6 and later
  indeo3: fix motion vector validation
  pcm_bluray: set bits_per_raw_sample for > 16-bit
  twinvq: fix out of bounds array access
  lavr: use 8.8 instead of 10.6 as the 16-bit fixed-point mixing coeff type
