		8. Obsolete functions
		8. Vendor and device identifications
		~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
		For the future, let's avoid adding device ids to include/linux/pci_ids.h.

		PCI_VENDOR_ID_xxx for vendors, and a hex constant for device ids.

		Rationale: PCI_VENDOR_ID_xxx constants are re-used, but device ids are not.
		Further, device ids are arbitrary hex numbers, normally used only in a
		single location, the pci_device_id table.

		9. Obsolete functions
		~~~~~~~~~~~~~~~~~~~~~
		There are several functions which you might come across when trying to
		port an old driver to the new PCI interface. They are no longer present
