[PATCH v2 REPOST 00/12] x86: guest resource mapping

[Paul Durrant <paul.durrant@citrix.com>]

(REPOST after rebase and reference fix in patch #4 comment)

This series introduces support for direct mapping of guest resources.
The resources are:
 - Grant tables
 - IOREQ server pages

Paul Durrant (12):
  [x86|arm]: remove code duplication
  x86/mm: allow a privileged PV domain to map guest mfns
  x86/mm: add HYPERVISOR_memory_op to acquire guest resources
  tools/libxenforeignmemory: add support for resource mapping
  tools/libxenctrl: use new xenforeignmemory API to seed grant table
  x86/hvm/ioreq: rename .*pfn and .*gmfn to .*gfn
  x86/hvm/ioreq: use bool rather than bool_t
  x86/hvm/ioreq: move is_default into struct hvm_ioreq_server
  x86/hvm/ioreq: simplify code and use consistent naming
  x86/hvm/ioreq: use gfn_t in struct hvm_ioreq_page
  x86/hvm/ioreq: defer mapping gfns until they are actually requsted
  x86/hvm/ioreq: add a new mappable resource type...
