Implementation details aside, you are agreeing that the
pci_alloc_consistent() interface can return an address > 4GB and we
can document as such?

I can return an address that matches the requirements specified by
dev->consistent_dma_mask which is set by default to 0xffffffff and
must be changed by a device driver if it wants to use a non-default
value.
