From: Juergen Gross <jgross@xxxxxxxx> [ Upstream commit 897919ad8b42eb8222553838ab82414a924694aa ] This configuration option provides a misc device as an API to userspace. Make this API usable without having to select the module as a transitive dependency. This also fixes an issue where localyesconfig would select CONFIG_XEN_PRIVCMD=m because it was not visible and defaulted to building as module.
