Merge remote-tracking branch 'sstabellini/xen-20121217' into staging

* sstabellini/xen-20121217:
  cpu_ioreq_pio, cpu_ioreq_move: i should be uint32_t rather than int
  cpu_ioreq_pio, cpu_ioreq_move: introduce read_phys_req_item, write_phys_req_item
  Fix compile errors when enabling Xen debug logging.
  xen: fix trivial PCI passthrough MSI-X bug
  xen: implement support for secondary consoles in the console backend
