Yeah, so I don't think it's obvious to people what the DQ/BW/VL extensions are 
precisely, so I changed the text to the following, a bit more verbose 
descriptions:

  #define X86_FEATURE_AVX512DQ  ( 9*32+17) /* AVX-512 DQ (Double/Quad granular) Instructions */
  #define X86_FEATURE_AVX512BW	( 9*32+30) /* AVX-512 BW (Byte/Word granular) Instructions */
  #define X86_FEATURE_AVX512VL	( 9*32+31) /* AVX-512 VL (128/256 Vector Length) Extensions */

Please holler if you disagree!

Thanks,

	Ingo
