* Xen: ARM: Zero reserved fields of xatp before making hypervisor callJiandi An2017-01-031-3/+5
| | | | | | | | | | | Ensure all reserved fields of xatp are zero before making hypervisor call to XEN in xen_map_device_mmio(). xenmem_add_to_physmap_one() in XEN fails the mapping request if extra.res reserved field in xatp is not zero for XENMAPSPACE_dev_mmio request.
