Okay, we do not generate P6 NOPs statically if CONFIG_X86_GENERIC_CPU is 
enabled -- unless, of course gcc/binutils generates them, which they now 
do for certain CPU types.  If you are selecting a specific CPU *and* you 
don't select GENERIC, you should get valid code for the selected CPU only.

As far as using them dynamically, there is code in -tip that determines 
dynamically and explicitly if the long NOPs are available, and only uses 
them if they are.
