It's a bit of a bummer that we're going to prompt everybody doing
oldconfig's for this new option.  But, I don't know any way for Kconfig
to suppress it if the name is changed.  Also, I guess the def_bool=y
means that menuconfig and olddefconfig will tend to do the right thing.

Do we *really* need to change the Kconfig name?  The text prompt, sure.
 End users see that and having Intel in there is massively confusing.

If I have to put up with seeing 'amd64' all over my Debian package
names, you can put up with a Kconfig name. :P

I'm really just wondering what the point of the churn is.
