[PATCH] PCI: Provide a boot parameter to disable MSI
Several drivers are starting to grow options to disable MSI. However,
it's often a host chipset issue, not something which individual drivers
should handle. So we add the pci=nomsi kernel parameter to allow the user
to disable MSI modes for systems we haven't added to the quirk list yet.
