the number that is exposed in /proc/cpuinfo does not control if cmov is used... so the patch and the benchmark are totally unrelated.
Anything that needs to know if cmov can be used will need to read the flags line..
(since technically cmov is also optional for generation 6 and later)
While I can't say anything against your patch, I do need to say that it is something purely cosmetic on first sight...
