Merge tag 'pci-v3.14-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaa...

Pull PCI updates from Bjorn Helgaas:
 "The most interesting thing here is the change to enable INTx (by
  clearing PCI_COMMAND_INTX_DISABLE) if the BIOS left INTx disabled.
  Apparently the Baytrail BIOS does this, which means EHCI doesn't work.

  Also, fix an AHCI MSI regression and other issues with the recent MSI
  changes.  This also adds pci_enable_msi_exact() and
  pci_enable_msix_exact(), which aren't regression fixes, but will keep
  us from touching drivers twice (once to stop using the deprecated
  pci_enable_msi(), etc., and again to use the *_exact() variants).

  There's also a minor MVEBU fix.

  Summary:

  MSI:
    - Fix AHCI single-MSI fallback (Alexander Gordeev)
    - Fix populate_msi_sysfs() error paths (Greg Kroah-Hartman)
    - Fix htmldocs problem (Masanari Iida)
    - Add pci_enable_msi_exact() and pci_enable_msix_exact() (Alexander Gordeev)
    - Update documentation (Alexander Gordeev)

  Miscellaneous:
    - mvebu: expose device ID & revision via lspci (Andrew Lunn)
    - Enable INTx if the BIOS left them disabled (Bjorn Helgaas)"
