* remotes/sstabellini/tags/xen-2015-09-10-tag: (29 commits)
  xen/pt: Don't slurp wholesale the PCI configuration registers
  xen/pt: Check for return values for xen_host_pci_[get|set] in init
  xen/pt: Move bulk of xen_pt_unregister_device in its own routine.
  xen/pt: Make xen_pt_unregister_device idempotent
  xen/pt: Log xen_host_pci_get/set errors in MSI code.
  xen/pt: Log xen_host_pci_get in two init functions
  xen/pt: Remove XenPTReg->data field.
  xen/pt: Check if reg->init function sets the 'data' past the reg->size
  xen/pt: Sync up the dev.config and data values.
  xen/pt: Use xen_host_pci_get_[byte|word] instead of dev.config
  xen/pt: Use XEN_PT_LOG properly to guard against compiler warnings.
  xen/pt/msi: Add the register value when printing logging and error messages
  xen: use errno instead of rc for xc_domain_add_to_physmap
  xen/pt: xen_host_pci_config_read returns -errno, not -1 on failure
  xen/pt: Make xen_pt_msi_set_enable static
  xen/pt: Update comments with proper function name.
  xen/HVM: atomically access pointers in bufioreq handling
  xen-hvm: When using xc_domain_add_to_physmap also include errno when reporting
  xen, gfx passthrough: add opregion mapping
  xen, gfx passthrough: register host bridge specific to passthrough
  ...
