- Instead of just including optimizations for the selected
- x86 variant (e.g. PII, Crusoe or Athlon), include some more
- generic optimizations as well. This will make the kernel
- perform better on x86 CPUs other than that selected.

- This is really intended for distributors who need more

+ Instead of just including optimizations and workarounds for
+ the selected x86 variant (e.g. PII, Crusoe or Athlon),
+ include some more generic optimizations and workarounds as
+ well. Without this option, the kernel is not guaranteed to
+ run on anything other than the exact CPU selected.

+ Disable this if you want to run the kernel on a specific CPU
+ *only* and want maximum optimizations for that CPU.
