  x86: cabac: change 'a' constraint to 'r' in get_cabac_inline()
  x86: cabac: remove hardcoded esi in get_cabac_inline()
  x86: cabac: remove hardcoded edx in get_cabac_inline()
  x86: cabac: remove unused macro parameter
  x86: cabac: remove hardcoded ebx in inline asm
  x86: cabac: remove hardcoded struct offsets from inline asm
  cabac: remove inline asm under #if 0
  cabac: remove BRANCHLESS_CABAC_DECODER switch
  cabac: remove #if 0 cascade under never-set #ifdef ARCH_X86_DISABLED
  document libswscale bump
  error_resilience: skip last-MV predictor step if MVs are not available.
  error_resilience: actually add counter when adding a MV predictor.
