    Subject[PATCH AUTOSEL 4.4 1/9] xen/privcmd: make option visible in Kconfig
    Date
    From: Juergen Gross <jgross@suse.com>

    [ 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.

    [boris: clarified help message per Jan's suggestion]
