Based on Ben's concerns, I dropped Yinghai's three patches for now:

PCI: Add pci_bus_addr_t
sparc/PCI: Parse 64-bit host bridge windows from OF
PCI: Allow non-prefetchable PCIe BARs in prefetchable windows

and reverted d63e2e1f3df9 ("sparc/PCI: Clip bridge windows to fit in
upstream windows") instead.

I pushed this to my for-linus branch, which I intend to merge for v4.0.

Dave, I know you weren't happy with this proposal the first time around,
but I'm not sure why. If you have a better idea, let me know.
