Pull PCI updates from Bjorn Helgaas:

 - add enhanced Downstream Port Containment support, which prints more
   details about Root Port Programmed I/O errors (Dongdong Liu)

 - add Layerscape ls1088a and ls2088a support (Hou Zhiqiang)

 - add MediaTek MT2712 and MT7622 support (Ryder Lee)

 - add MediaTek MT2712 and MT7622 MSI support (Honghui Zhang)

 - add Qualcom IPQ8074 support (Varadarajan Narayanan)

 - add R-Car r8a7743/5 device tree support (Biju Das)

 - add Rockchip per-lane PHY support for better power management (Shawn
   Lin)

 - fix IRQ mapping for hot-added devices by replacing the
   pci_fixup_irqs() boot-time design with a host bridge hook called at
   probe-time (Lorenzo Pieralisi, Matthew Minter)

 - fix race when enabling two devices that results in upstream bridge
   not being enabled correctly (Srinath Mannam)

 - fix pciehp power fault infinite loop (Keith Busch)

 - fix SHPC bridge MSI hotplug events by enabling bus mastering
   (Aleksandr Bezzubikov)

 - fix a VFIO issue by correcting PCIe capability sizes (Alex
   Williamson)

 - fix an INTD issue on Xilinx and possibly other drivers by unifying
   INTx IRQ domain support (Paul Burton)

 - avoid IOMMU stalls by marking AMD Stoney GPU ATS as broken (Joerg
   Roedel)

 - allow APM X-Gene device assignment to guests by adding an ACS quirk
   (Feng Kan)

 - fix driver crashes by disabling Extended Tags on Broadcom HT2100
   (Extended Tags support is required for PCIe Receivers but not
   Requesters, and we now enable them by default when Requesters support
   them) (Sinan Kaya)

 - fix MSIs for devices that use phantom RIDs for DMA by assuming MSIs
   use the real Requester ID (not a phantom RID) (Robin Murphy)

 - prevent assignment of Intel VMD children to guests (which may be
   supported eventually, but isn't yet) by not associating an IOMMU with
   them (Jon Derrick)

 - fix Intel VMD suspend/resume by releasing IRQs on suspend (Scott
   Bauer)

 - fix a Function-Level Reset issue with Intel 750 NVMe by waiting
   longer (up to 60sec instead of 1sec) for device to become ready
   (Sinan Kaya)

 - fix a Function-Level Reset issue on iProc Stingray by working around
   hardware defects in the CRS implementation (Oza Pawandeep)

 - fix an issue with Intel NVMe P3700 after an iProc reset by adding a
   delay during shutdown (Oza Pawandeep)

 - fix a Microsoft Hyper-V lockdep issue by polling instead of blocking
   in compose_msi_msg() (Stephen Hemminger)

 - fix a wireless LAN driver timeout by clearing DesignWare MSI
   interrupt status after it is handled, not before (Faiz Abbas)

 - fix DesignWare ATU enable checking (Jisheng Zhang)

 - reduce Layerscape dependencies on the bootloader by doing more
   initialization in the driver (Hou Zhiqiang)

 - improve Intel VMD performance allowing allocation of more IRQ vectors
   than present CPUs (Keith Busch)

 - improve endpoint framework support for initial DMA mask, different
   BAR sizes, configurable page sizes, MSI, test driver, etc (Kishon
   Vijay Abraham I, Stan Drozd)

 - rework CRS support to add periodic messages while we poll during
   enumeration and after Function-Level Reset and prepare for possible
   other uses of CRS (Sinan Kaya)

 - clean up Root Port AER handling by removing unnecessary code and
   moving error handler methods to struct pcie_port_service_driver
   (Christoph Hellwig)

 - clean up error handling paths in various drivers (Bjorn Andersson,
   Fabio Estevam, Gustavo A. R. Silva, Harunobu Kurokawa, Jeffy Chen,
   Lorenzo Pieralisi, Sergei Shtylyov)

 - clean up SR-IOV resource handling by disabling VF decoding before
   updating the corresponding resource structs (Gavin Shan)

 - clean up DesignWare-based drivers by unifying quirks to update Class
   Code and Interrupt Pin and related handling of write-protected
   registers (Hou Zhiqiang)

 - clean up by adding empty generic pcibios_align_resource() and
   pcibios_fixup_bus() and removing empty arch-specific implementations
   (Palmer Dabbelt)

 - request exclusive reset control for several drivers to allow cleanup
   elsewhere (Philipp Zabel)

 - constify various structures (Arvind Yadav, Bhumika Goyal)

 - convert from full_name() to %pOF (Rob Herring)

 - remove unused variables from iProc, HiSi, Altera, Keystone (Shawn
   Lin)

582ffae852 PCI: xgene: Define XGENE_PCI_EXP_CAP and use generic PCI_EXP_RTCTL offset
Apparently the PCIe capability is at address 0x40 in config space of X-Gene
v1 Root Ports.  Add a definition of that and use the generic PCI_EXP_RTCTL
offset into the capability.  No functional change intended.

53ac64aac9 ACPI updates for v4.14-rc1
- Update the ACPICA code in the kernel to upstream revision 20170728
    including:
    * Alias operator handling update (Bob Moore).
    * Deferred resolution of reference package elements (Bob Moore).
    * Support for the _DMA method in walk resources (Bob Moore).
    * Tables handling update and support for deferred table
      verification (Lv Zheng).
    * Update of SMMU models for IORT (Robin Murphy).
    * Compiler and disassembler updates (Alex James, Erik Schmauss,
      Ganapatrao Kulkarni, James Morse).
    * Tools updates (Erik Schmauss, Lv Zheng).
    * Assorted minor fixes and cleanups (Bob Moore, Kees Cook,
      Lv Zheng, Shao Ming).
 
  - Rework the initialization of non-wakeup GPEs with method handlers
    in order to address a boot crash on some systems with Thunderbolt
    devices connected at boot time where we miss an early hotplug
    event due to a delay in GPE enabling (Rafael Wysocki).
 
  - Rework the handling of PCI bridges when setting up ACPI-based
    device wakeup in order to avoid disabling wakeup for bridges
    prematurely (Rafael Wysocki).
 
  - Consolidate Apple DMI checks throughout the tree, add support for
    Apple device properties to the device properties framework and
    use these properties for the handling of I2C and SPI devices on
    Apple systems (Lukas Wunner).
 
  - Add support for _DMA to the ACPI-based device properties lookup
    code and make it possible to use the information from there to
    configure DMA regions on ARM64 systems (Lorenzo Pieralisi).
 
  - Fix several issues in the APEI code, add support for exporting
    the BERT error region over sysfs and update APEI MAINTAINERS
    entry with reviewers information (Borislav Petkov, Dongjiu Geng,
    Loc Ho, Punit Agrawal, Tony Luck, Yazen Ghannam).
 
  - Fix a potential initialization ordering issue in the ACPI EC
    driver and clean it up somewhat (Lv Zheng).
 
  - Update the ACPI SPCR driver to extend the existing XGENE 8250
    workaround in it to a new platform (m400) and to work around
    an Xgene UART clock issue (Graeme Gregory).
 
  - Add a new utility function to the ACPI core to support using
    ACPI OEM ID / OEM Table ID / Revision for system identification
    in blacklisting or similar and switch over the existing code
    already using this information to this new interface (Toshi Kani).
 
  - Fix an xpower PMIC issue related to GPADC reads that always return
    0 without extra pin manipulations (Hans de Goede).
 
  - Add statements to print debug messages in a couple of places in
    the ACPI core for easier diagnostics (Rafael Wysocki).
 
  - Clean up the ACPI processor driver slightly (Colin Ian King,
    Hanjun Guo).
 
  - Clean up the ACPI x86 boot code somewhat (Andy Shevchenko).
 
  - Add a quirk for Dell OptiPlex 9020M to the ACPI backlight
    driver (Alex Hung).
 
  - Assorted fixes, cleanups and updates related to ACPI (Amitoj Kaur
    Chawla, Bhumika Goyal, Frank Rowand, Jean Delvare, Punit Agrawal,
    Ronald Tschalär, Sumeet Pawnikar).
