- List-id: Xen developer discussion <xen-devel.lists.xenproject.org>
So that it doesn't break the build when CONFIG_XEN or CONFIG_XEN_DOM0
are not enabled.
The current header is only included when CONFIG_XEN_DOM0 is selected,
so instead place it in the top level xen.h header, and also use the
dummy helper when CONFIG_X86 is not selected, as the current
implementation is x86 only.
