    PCI/AER: Remove aerdriver.forceload kernel parameter · 7ece1417
    Bjorn Helgaas authored
    Per the PCI Firmware spec, r3.0, sec 4.5.1, on ACPI systems, the OS must
    not use AER unless _OSC is present and _OSC grants AER control to the OS.
    The aerdriver.forceload kernel parameter was a way to enable Linux AER
    support on ACPI systems that lack _OSC or fail to grant control the the OS.
    Enabling Linux AER support when the firmware doesn't want us to is a recipe
    for problems, e.g., the firmware might be handling AER itself.
    Remove the aerdriver.forceload kernel parameter and related supporting
