PCI: improve resource allocation under transparent bridges
We could run out of space under under 4g, but devices under transparent bridges can use 64bit resources, so keep trying on the parent bus until we hit a non-transparent bridge. Impact: better support for assigning unassigned resources Reviewed-by: Ivan Kokshaysky <ink@jurassic.park.msu.ru> Signed-off-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
