Was the origin of this patch the following thread started
by John Linville:
http://lkml.org/lkml/2005/6/23/257

I pointed out it would have issues with 64-bit BARs.
And I suggested some solutions to JohnL's patch here:
http://lkml.org/lkml/2005/7/2/14

In any case same issues apply to pci_update_resource().
