Ok, on that basis I won't try to convert it to AND ;-)

Seriously though, there's two other 32-bit prefix cleanup/micro-speedup changes 
I'll queue up later today:

  [PATCH v2] x86-64: use 32-bit XOR to zero registers
  [PATCH] x86/entry/64: add two more instruction suffixes

I'll Cc: you guys on the commits and maybe you can find something weird (or leet) 
in them as well.

Thanks,
