[Xen-devel] Sync domctl.h for XEN_DOMCTL_subscribe

["KUWAMURA Shin'ya" <kuwa@xxxxxxxxxxxxxx>]

Hi,

On ia64, saving PV domains and HVM domains with PV-on-HVM drivers
fail with the following error:
  xc_save: failed to subscribe to domain: -1

This patch is required for adding XEN_DOMCTL_subscribe to xencomm in
order to support ia64.
