Pull more PCI updates from Bjorn Helgaas:
 "Here are some more things I'd like to see in v3.16-rc1:

   - DMA alias iterator, part of some work to fix IOMMU issues

   - Some whitespace code cleanup

  Details:

  IOMMU
    - Add DMA alias iterator (Alex Williamson)
    - Add DMA alias quirks for ASMedia, ITE, Tundra bridges (Alex Williamson)
    - Add DMA alias quirks for Marvell, Ricoh devices (Alex Williamson)
    - Add DMA alias quirk for HighPoint devices (Jérôme Carretero)

  MSI
    - Fix leak in free_msi_irqs() (Alexei Starovoitov)

  Marvell MVEBU
    - Remove unnecessary use of 'conf_lock' spinlock (Andrew Murray)
    - Avoid setting an undefined window size (Jason Gunthorpe)
    - Allow several windows with the same target/attribute (Thomas Petazzoni)
    - Split PCIe BARs into multiple MBus windows when needed (Thomas Petazzoni)
    - Fix off-by-one in the computed size of the mbus windows (Willy Tarreau)

  NVIDIA Tegra
    - Use new OF interrupt mapping when possible (Lucas Stach)

  Synopsys DesignWare
    - Remove unnecessary use of 'conf_lock' spinlock (Andrew Murray)
    - Use new OF interrupt mapping when possible (Lucas Stach)
    - Split Exynos and i.MX bindings (Lucas Stach)
    - Fix comment for setting number of lanes (Mohit Kumar)
    - Fix iATU programming for cfg1, io and mem viewport (Mohit Kumar)

  Miscellaneous
    - EXPORT_SYMBOL cleanup (Ryan Desfosses)
    - Whitespace cleanup (Ryan Desfosses)
    - Merge multi-line quoted strings (Ryan Desfosses)"
