Oh, hrm.  Yes, there is.  But why is this better ?

One reason for all this Kconfig stuff is to be able to disable unused
interfaces for security reasons.  That also means being able to easily
audit what interfaces are enabled, which is a lot simpler if you can
read the main switch statement for the relevant hypercall, than if you
have to go chasing off after definitions.
