    Linus Torvalds authored
    Pull PCI updates from Bjorn Helgaas:
     - move pci_uevent_ers() out of pci.h (Michael Ellerman)
     - skip ASPM common clock warning if BIOS already configured it (Sinan
     - fix ASPM Coverity warning about threshold_ns (Gustavo A. R. Silva)

       (Sinan Kaya)
     - add decoding for 16 GT/s link speed (Jay Fang)

     - add pcie_bandwidth_capable() to compute max supported link bandwidth
       (Tal Gilboa)
     - add pcie_bandwidth_available() to compute bandwidth available to
       device (Tal Gilboa)
     - add pcie_print_link_status() to log link speed and whether it's
       limited (Tal Gilboa)
     - use PCI core interfaces to report when device performance may be
       limited by its slot instead of doing it in each driver (Tal Gilboa)

       hotplug (Mika Westerberg)
     - add support for PCI I/O port space that's neither directly accessible
       via CPU in/out instructions nor directly mapped into CPU physical
       memory space. This is fairly intrusive and includes minor changes to
       interfaces used for I/O space on most platforms (Zhichang Yuan, John
     - add support for HiSilicon Hip06/Hip07 LPC I/O space (Zhichang Yuan,
       John Garry)

       ia64, and mn10300 with x86 (Bjorn Helgaas)
     - move pcieport_if.h to drivers/pci/pcie/ to encapsulate it (Frederick
     - merge pcieport_if.h into portdrv.h (Bjorn Helgaas)
     - move workaround for BIOS PME issue from portdrv to PCI core (Bjorn
     - completely disable portdrv with "pcie_ports=compat" (Bjorn Helgaas)
     - remove portdrv link order dependency (Bjorn Helgaas)
     - remove support for unused VC portdrv service (Bjorn Helgaas)
     - simplify portdrv feature permission checking (Bjorn Helgaas)
     - remove "pcie_hp=nomsi" parameter (use "pci=nomsi" instead) (Bjorn
     - remove unnecessary "pcie_ports=auto" parameter (Bjorn Helgaas)
     - use cached AER capability offset (Frederick Lawler)
     - don't enable DPC if BIOS hasn't granted AER control (Mika Westerberg)
     - rename pcie-dpc.c to dpc.c (Bjorn Helgaas)
     - use generic pci_mmap_resource_range() instead of powerpc and xtensa
       arch-specific versions (David Woodhouse)
     - support arbitrary PCI host bridge offsets on sparc (Yinghai Lu)
     - remove System and Video ROM reservations on sparc (Bjorn Helgaas)

     - handle failure of FLR gracefully (Sinan Kaya)
     - handle CRS (config retry status) after device resets (Sinan Kaya)
     - skip various config reads for SR-IOV VFs as an optimization
       (KarimAllah Ahmed)
     - consolidate VPD code in vpd.c (Bjorn Helgaas)
     - add Tegra dependency on PCI_MSI_IRQ_DOMAIN (Arnd Bergmann)
     - add DT support for R-Car r8a7743 (Biju Das)
     - fix a PCI_EJECT vs PCI_BUS_RELATIONS race condition in Hyper-V host
       bridge driver that causes a general protection fault (Dexuan Cui)
     - fix Hyper-V host bridge hang in MSI setup on 1-vCPU VMs with SR-IOV
