This header is now only for native Xen code, not PV backends that may be used in Xen emulation. Since the toolstack libraries may depend on the specific version of Xen headers that they pull in (and will set the __XEN_TOOLS__ macro to enable internal definitions that they depend on), the rule is that xen_native.h (and thus the toolstack library headers) must be included *before* any of the headers in include/hw/xen/interface.
