[Xen-devel] [PATCH v9 2/5] x86/ioreq server: Add DMOP to map guest ram with p2m_ioreq_server to an ioreq server.

A new DMOP - XEN_DMOP_map_mem_type_to_ioreq_server, is added to let one ioreq server claim/disclaim its responsibility for the handling of guest pages with p2m type p2m_ioreq_server. Users of this DMOP can specify which kind of operation is supposed to be emulated in a parameter named flags.
