    Subject[PATCH v1 0/9] PCI: Simplify PCIe port driver
    From
    Date
    This is an attempt to move a few things out of the port driver.

    Patches 1-2 move a workaround for a BIOS PME issue from the port driver to
    the PCI core, so it doesn't depend on CONFIG_PCIEPORTBUS.

    Patch 3 extends that workaround so it works for Root Complex Event
    Collectors. I haven't seen reports of this being a problem, but I think we
    should handle Event Collector PMEs the same as Root Port PMEs.

    Patch 4 disables the port driver completely for "pcie_ports=compat". We
    used to register the driver, claim port devices, enable them, etc., as part
    of supporting the above BIOS workaround.

    Patch 5 removes a port driver link order dependency.

    Patch 6 removes the unused VC service.

    Patch 7 simplifies the _OSC code path by keeping more of the details in the
    ACPI pci_root.c driver.

    Patch 8 removes an unnecessary #include.

    Patch 9 removes the "pcie_hp=nomsi" parameter. This was added to work
    around an issue when shutting down devices, but a later patch fixed the
    root cause, and I don't think we need such a specific parameter any more
    (we still have "pci=nomsi").
