The issue at hand is that at least with the current toolchain, we need
to pass -march=generic in order for these instructions to be generated.
We have an option for this, CONFIG_X86_GENERIC, which distributions
really *should* be using anyway.
And yes, it should be the default. The patch I have makes it
"default y" as well as change the help text.
Would it make you happier if this option was forced enabled unless
CONFIG_EMBEDDED was on?
