commit 3486f398a3ddea81ea8c67be981ce31d52036b3a
Author: Paul Durrant <paul.durrant@xxxxxxxxxx>

    x86/hvm/ioreq: allow ioreq servers to use HVM_PARAM_[BUF]IOREQ_PFN
    Since commit 2c257bd6 "x86/hvm: remove default ioreq server (again)" the
    GFNs allocated by the toolstack and set in HVM_PARAM_IOREQ_PFN and
    HVM_PARAM_BUFIOREQ_PFN have been unused. This patch allows them to be used
    by (non-default) ioreq servers.
    While in the area, also make sure HVM_PARAM_[BUF]IOREQ_PFN can only be set
    once. These parameters should have always been in the 'set once' category
    but this has, so far, not been enforced.
    NOTE: This fixes a compatibility issue. A guest created on a version of
          Xen that pre-dates the initial ioreq server implementation and then
          migrated in will currently fail to resume because its migration
          stream will lack values for HVM_PARAM_IOREQ_SERVER_PFN and
          HVM_PARAM_NR_IOREQ_SERVER_PAGES *unless* the system has an
          emulator domain that uses direct resource mapping (which depends
          on the version of privcmd it happens to have) in which case it
          will not require use of GFNs for the ioreq server shared
