We want to convert all code to use a single interface for testing CPU features
- cpu_feature_enabled() - and the implementation shouldn't be important to
users - it should just work.

Since you're adding new code, you might as well use the proper interface. As
to converting crypto/ and the rest of the tree, that should happen at some
point... eventually...

Thx.
