The -mcpu=pentiumpro and -march=pentiumpro mean generate code optimised

advantage in using both and they may even conflict. For an Athlon, the
flag you want is -march=k6.

Actually, the Athlon is a "K7" device, which likes optimizations more akin to
a Pentium 3 than to a k6 CPU.

If you configure your own kernel with xconfig (and probably menuconfig
too), you get the option of specifying what kind of architecture you
have and the configuration automatically gives you sensible
optimisations. It is unwise to try to do more unless you really know
what you are doing.

Agreed 100%.
