- List-id: Xen developer discussion <xen-devel.lists.xenproject.org>
A later patch removes boot_module and replaces its uses with bootmodule.
The equivalent field for "type" doesn't have BOOTMOD_UNKNOWN as a zero
value, so it must be explicitly set in the static xen_boot_info.
Not a functional change.
