Merge branch 'pci/hotplug'

  - Differentiate between pciehp surprise and safe removal (Lukas Wunner)

  - Remove unnecessary pciehp includes (Lukas Wunner)

  - Drop pciehp hotplug_slot_ops wrappers (Lukas Wunner)

  - Tolerate PCIe Slot Presence Detect being hardwired to zero to
    workaround broken hardware, e.g., the Wilocity switch/wireless device
    (Lukas Wunner)

  - Unify pciehp controller & slot structs (Lukas Wunner)

  - Constify hotplug_slot_ops (Lukas Wunner)

  - Drop hotplug_slot_info (Lukas Wunner)

  - Embed hotplug_slot struct into users instead of allocating it
    separately (Lukas Wunner)

  - Initialize PCIe port service drivers directly instead of relying on
    initcall ordering (Keith Busch)

  - Restore PCI config state after a slot reset (Keith Busch)

  - Save/restore DPC config state along with other PCI config state (Keith
    Busch)

  - Reference count devices during AER handling to avoid race issue with
    concurrent hot removal (Keith Busch)

  - If an Upstream Port reports ERR_FATAL, don't try to read the Port's
    config space because it is probably unreachable (Keith Busch)

  - During error handling, use slot-specific reset instead of secondary
    bus reset to avoid link up/down issues on hotplug ports (Keith Busch)

  - Restore previous AER/DPC handling that does not remove and re-enumerate
    devices on ERR_FATAL (Keith Busch)

  - Notify all drivers that may be affected by error recovery resets (Keith
    Busch)

  - Always generate error recovery uevents, even if a driver doesn't have
    error callbacks (Keith Busch)

  - Make PCIe link active reporting detection generic (Keith Busch)

  - Support D3cold in PCIe hierarchies during system sleep and runtime,
    including hotplug and Thunderbolt ports (Mika Westerberg)

  - Handle hpmemsize/hpiosize kernel parameters uniformly, whether slots
    are empty or occupied (Jon Derrick)

  - Remove duplicated include from pci/pcie/err.c and unused variable from
    cpqphp (YueHaibing)

  - Remove driver pci_cleanup_aer_uncorrect_error_status() calls (Oza
    Pawandeep)

  - Uninline PCI bus accessors for better ftracing (Keith Busch)

  - Remove unused AER Root Port .error_resume method (Keith Busch)

  - Use kfifo in AER instead of a local version (Keith Busch)

  - Use threaded IRQ in AER bottom half (Keith Busch)

  - Use managed resources in AER core (Keith Busch)

  - Reuse pcie_port_find_device() for AER injection (Keith Busch)

  - Abstract AER interrupt handling to disconnect error injection (Keith
    Busch)

  - Refactor AER injection callbacks to simplify future improvments (Keith
    Busch)
