As far as I can tell, you didn't actually add anything that uses
pcix_bus_speed[].
You added a pcie_link_speed[] use only in drivers/pci/pci.c; maybe
this extern declaration could go in drivers/pci/pci.h to limit its
visibility?
If you update this patch, note that we conventionally capitalize "PCI:
Expose ..." in the changelog summary, e.g., "git log --oneline
drivers/pci".
