The Intel documentation at
http://software.intel.com/file/36945
shows the ANDN opcode and Group 17 with encoding f2 and f3 encoding
respectively. The current version of x86-opcode-map.txt shows them
with f3 and f4. Unless someone can point to documentation which shows
the currently used encoding the following patch be applied.

I work for Intel. I don't speak on their behalf.
